Data Sheet

High-Performance,

16-bit Digital Signal Controllers

DS70139G

Note the following details of the code protection feature on Microchip devices:

•

Microchip products meet the specification contained in their particular Microchip Data Sheet.

•

Microchip believes that its family of products is one of the most secure families of its kind on the market today, when used in the

intended manner and under normal conditions.

•

There are dishonest and possibly illegal methods used to breach the code protection feature. All of these methods, to our

knowledge, require using the Microchip products in a manner outside the operating specifications contained in Microchip’s Data

Sheets. Most likely, the person doing so is engaged in theft of intellectual property.

•

Microchip is willing to work with the customer who is concerned about the integrity of their code.

Neither Microchip nor any other semiconductor manufacturer can guarantee the security of their code. Code protection does not

mean that we are guaranteeing the product as “unbreakable.”

Code protection is constantly evolving. We at Microchip are committed to continuously improving the code protection features of our

products. Attempts to break Microchip’s code protection feature may be a violation of the Digital Millennium Copyright Act. If such acts

allow unauthorized access to your software or other copyrighted work, you may have a right to sue for relief under that Act.

Information contained in this publication regarding device

applications and the like is provided only for your convenience

and may be superseded by updates. It is your responsibility to

ensure that your application meets with your specifications.

Note:

This data sheet summarizes features of

this group of dsPIC30F devices and is not

intended to be a complete reference

source. For more information on the CPU,

peripherals, register descriptions and

general device functionality, refer to the

“dsPIC30F Family Reference Manual”

(DS70046). For more information on the

device instruction set and programming,

refer to the “16-bit MCU and DSC

program space at any 16K program word

boundary, defined by the 8-bit Program Space

Visibility Page register (PSVPAG). Thus any

instruction can access program space as if it were

data space, with a limitation that the access

requires an additional cycle. Only the lower 16

bits of each instruction word can be accessed

using this method.

• Linear indirect access of 32K word pages within

program space is also possible using any working

register, via table read and write instructions.

Table read and write instructions can be used to

access all 24 bits of an instruction word.

Programmer’s

Reference

Manual”

(DS70157).

This section is an overview of the CPU architecture of

the dsPIC30F. The core has a 24-bit instruction word.

The Program Counter (PC) is 23 bits wide with the

Least Significant bit (LSb) always clear (see

Section 3.1 “Program Address Space”). The Most

Significant bit (MSb) is ignored during normal program

execution, except for certain specialized instructions.

Thus, the PC can address up to 4M instruction words

of user program space. An instruction prefetch

mechanism helps maintain throughput. Program loop

constructs, free from loop count management

overhead, are supported using the DO and REPEAT

instructions, both of which are interruptible at any point.

Overhead-free circular buffers (Modulo Addressing)

are supported in both X and Y address spaces. This is

primarily intended to remove the loop overhead for

DSP algorithms.

The X AGU also supports Bit-Reversed Addressing on

destination effective addresses to greatly simplify input

or output data reordering for radix-2 FFT algorithms.

Refer to Section 4.0 “Address Generator Units” for

details on Modulo and Bit-Reversed Addressing.

The core supports Inherent (no operand), Relative,

Literal, Memory Direct, Register Direct, Register

Indirect, Register Offset and Literal Offset Addressing

modes. Instructions are associated with pre-defined

addressing modes, depending upon their functional

requirements.

2.1

Core Overview

The working register array consists of 16 x 16-bit

registers, each of which can act as data, address or

offset registers. One working register (W15) operates

as a Software Stack Pointer for interrupts and calls.

For most instructions, the core is capable of executing

a data (or program data) memory read, a working

register (data) read, a data memory write and a

program (instruction) memory read per instruction

The data space is 64 Kbytes (32K words) and is split

into two blocks, referred to as X and Y data memory.

Each block has its own independent Address Genera-

tion Unit (AGU). Most instructions operate solely

through the X memory, AGU, which provides the

appearance of a single unified data space. The

Multiply-Accumulate (MAC) class of dual source DSP

instructions operate through both the X and Y AGUs,

splitting the data address space into two parts (see

Section 3.2 “Data Address Space”). The X and Y

data space boundary is device specific and cannot be

altered by the user. Each data word consists of 2 bytes

and most instructions can address data either as words

or bytes.

cycle. As

a result, 3 operand instructions are

supported, allowing C = A+B operations to be exe-

cuted in a single cycle.

A DSP engine has been included to significantly

enhance the core arithmetic capability and throughput.

It features a high-speed 17-bit by 17-bit multiplier, a

40-bit ALU, two 40-bit saturating accumulators and a

40-bit bidirectional barrel shifter. Data in the

accumulator or any working register can be shifted up

to 15 bits right, or 16 bits left in a single cycle. The DSP

instructions operate seamlessly with all other

instructions and have been designed for optimal

real-time performance. The MAC class of instructions

can concurrently fetch two data operands from memory

while multiplying two W registers. To enable this

concurrent fetching of data operands, the data space

has been split for these instructions and linear is for all

others. This has been achieved in a transparent and

flexible manner, by dedicating certain working registers

to each address space for the MAC

class of

instructions.

DS70139G-page 19

dsPIC30F2011/2012/3012/3013

The core does not support a multi-stage instruction

pipeline. However, a single-stage instruction prefetch

mechanism is used, which accesses and partially

decodes instructions a cycle ahead of execution, in

order to maximize available execution time. Most

instructions execute in a single cycle with certain

exceptions.

2.2.1

SOFTWARE STACK POINTER/

FRAME POINTER

The dsPIC^®DSC devices contain a software stack.

W15 is the dedicated Software Stack Pointer (SP),

which is automatically modified by exception

processing and subroutine calls and returns. However,

W15 can be referenced by any instruction in the same

manner as all other W registers. This simplifies the

reading, writing and manipulation of the Stack Pointer

(e.g., creating stack frames).

The core features a vectored exception processing

structure for traps and interrupts, with 62 independent

vectors. The exceptions consist of up to 8 traps (of

which 4 are reserved) and 54 interrupts. Each interrupt

is prioritized based on a user-assigned priority between

1 and 7 (1 being the lowest priority and 7 being the

highest), in conjunction with a predetermined ‘natural

order’. Traps have fixed priorities ranging from 8 to 15.

Note:

In order to protect against misaligned

stack accesses, W15<0> is always clear.

W15 is initialized to 0x0800 during a Reset. The user

may reprogram the SP during initialization to any

location within data space.

2.2

Programmer’s Model

W14 has been dedicated as a Stack Frame Pointer, as

defined by the LNK and ULNK instructions. However,

W14 can be referenced by any instruction in the same

manner as all other W registers.

The programmer’s model is shown in Figure 2-1 and

consists of 16 x 16-bit working registers (W0 through

W15), 2 x 40-bit accumulators (ACCA and ACCB),

STATUS register (SR), Data Table Page register

(TBLPAG), Program Space Visibility Page register

(PSVPAG), DO and REPEAT registers (DOSTART,

DOEND, DCOUNT and RCOUNT) and Program Coun-

ter (PC). The working registers can act as data,

address or offset registers. All registers are memory

mapped. W0 acts as the W register for file register

addressing.

2.2.2

STATUS REGISTER

The dsPIC DSC core has a 16-bit STATUS register

(SR), the LSB of which is referred to as the SR Low

byte (SRL) and the MSB as the SR High byte (SRH).

See Figure 2-1 for SR layout.

SRL contains all the MCU ALU operation Status flags

(including the Z bit), as well as the CPU Interrupt

Priority Level Status bits, IPL<2:0>, and the Repeat

Active Status bit, RA. During exception processing,

SRL is concatenated with the MSB of the PC to form a

complete word value which is then stacked.

Some of these registers have a shadow register asso-

ciated with each of them, as shown in Figure 2-1. The

shadow register is used as a temporary holding register

and can transfer its contents to or from its host register

upon the occurrence of an event. None of the shadow

registers are accessible directly. The following rules

apply for transfer of registers into and out of shadows.

The upper byte of the STATUS register contains the

DSP Adder/Subtracter Status bits, the DO Loop Active

bit (DA) and the Digit Carry (DC) Status bit.

• PUSH.Sand POP.S

2.2.3

PROGRAM COUNTER

W0, W1, W2, W3, SR (DC, N, OV, Z and C bits

only) are transferred.

The program counter is 23 bits wide; bit 0 is always

clear. Therefore, the PC can address up to 4M

instruction words.

• DOinstruction

DOSTART, DOEND, DCOUNT shadows are

pushed on loop start and popped on loop end.

When a byte operation is performed on a working reg-

ister, only the Least Significant Byte (LSB) of the target

register is affected. However, a benefit of memory

mapped working registers is that both the Least and

Most Significant Bytes (MSB) can be manipulated

through byte-wide data memory space accesses.

The divide instructions must be executed within a

REPEAT loop. Any other form of execution

(e.g., a series of discrete divide instructions) will not

function correctly because the instruction flow depends

on RCOUNT. The divide instruction does not

automatically set up the RCOUNT value and it must,

therefore, be explicitly and correctly specified in the

REPEAT instruction, as shown in Table 2-1 (REPEAT

executes the target instruction {operand value+1}

times). The REPEAT loop count must be setup for 18

iterations of the DIV/DIVF instruction. Thus, a

complete divide operation requires 19 cycles.

2.3

Divide Support

The dsPIC DSC devices feature a 16/16-bit signed

fractional divide operation, as well as 32/16-bit and

16/16-bit signed and unsigned integer divide opera-

tions, in the form of single instruction iterative divides.

The following instructions and data sizes are

supported:

1. DIVF- 16/16 signed fractional divide

2. DIV.sd- 32/16 signed divide

3. DIV.ud- 32/16 unsigned divide

4. DIV.s- 16/16 signed divide

5. DIV.u- 16/16 unsigned divide

Note:

The divide flow is interruptible; however,

the user needs to save the context as

appropriate.

The 16/16 divides are similar to the 32/16 (same number

of iterations), but the dividend is either zero-extended or

sign-extended during the first iteration.

and saturation logic).

a

1. Fractional or integer DSP multiply (IF).

2. Signed or unsigned DSP multiply (US).

3. Conventional or convergent rounding (RND).

4. Automatic saturation on/off for ACCA (SATA).

The dsPIC30F is a single-cycle instruction flow

architecture, therefore, concurrent operation of the

DSP engine with MCU instruction flow is not possible.

However, some MCU ALU and DSP engine resources

may be used concurrently by the same instruction

(e.g., ED, EDAC). See Table 2-2.

MULTIPLIER

2.4.2.1

Adder/Subtracter, Overflow and

Saturation

The 17 x 17-bit multiplier is capable of signed or

unsigned operation and can multiplex its output using a

scaler to support either 1.31 fractional (Q31) or 32-bit

integer results. Unsigned operands are zero-extended

into the 17th bit of the multiplier input value. Signed

operands are sign-extended into the 17th bit of the

multiplier input value. The output of the 17 x 17-bit

The adder/subtracter is a 40-bit adder with an optional

zero input into one side and either true or complement

data into the other input. In the case of addition, the

carry/borrow input is active high and the other input is

true data (not complemented), whereas in the case of

subtraction, the carry/borrow input is active low and the

other input is complemented. The adder/subtracter

generates overflow status bits SA/SB and OA/OB,

which are latched and reflected in the STATUS register:

multiplier/scaler is

a

33-bit value which is

sign-extended to 40 bits. Integer data is inherently

represented as a signed two’s complement value,

where the MSB is defined as a sign bit. Generally

speaking, the range of an N-bit two’s complement

integer is -2^N-1to 2^N-1– 1. For a 16-bit integer, the data

range is -32768 (0x8000) to 32767 (0x7FFF) including

• Overflow from bit 39: This is a catastrophic

overflow in which the sign of the accumulator is

destroyed.

• Overflow into guard bits 32 through 39: This is a

recoverable overflow. This bit is set whenever all

the guard bits are not identical to each other.

‘0’. For

a

32-bit integer, the data range is

-2,147,483,648 (0x8000 0000) to 2,147,483,645

(0x7FFF FFFF).

The adder has an additional saturation block which

controls accumulator data saturation if selected. It uses

the result of the adder, the overflow Status bits

described above, and the mode control bits SATA/B

(CORCON<7:6>) and ACCSAT (CORCON<4>) to

determine when and to what value to saturate.

When the multiplier is configured for fractional

multiplication, the data is represented as a two’s

complement fraction, where the MSB is defined as a

sign bit and the radix point is implied to lie just after the

sign bit (QX format). The range of an N-bit two’s

complement fraction with this implied radix point is -1.0

to (1 – 2^1-N). For a 16-bit fraction, the Q15 data range

is -1.0 (0x8000) to 0.999969482 (0x7FFF) including ‘0’

and has a precision of 3.01518x10^-5. In Fractional

mode, the 16x16 multiply operation generates a 1.31

Six STATUS register bits have been provided to

support saturation and overflow. They are:

• OA: ACCA overflowed into guard bits

• OB: ACCB overflowed into guard bits

product, which has a precision of 4.65661 x 10^-10

.

• SA: ACCA saturated (bit 31 overflow and

saturation)

or

ACCA overflowed into guard bits and saturated

(bit 39 overflow and saturation)

The same multiplier is used to support the MCU

multiply instructions, which include integer 16-bit

signed, unsigned and mixed sign multiplies.

The MUL instruction can be directed to use byte or

word-sized operands. Byte operands direct a 16-bit

result. Word operands direct a 32-bit result to the

specified register(s) in the W array.

• SB: ACCB saturated (bit 31 overflow and

saturation)

or

ACCB overflowed into guard bits and saturated

(bit 39 overflow and saturation)

2.4.2

DATA ACCUMULATORS AND

ADDER/SUBTRACTER

• OAB: Logical OR of OA and OB

• SAB: Logical OR of SA and SB

The data accumulator consists of

a

40-bit

adder/subtracter with automatic sign extension logic. It

can select one of two accumulators (A or B) as its

pre-accumulation source and post-accumulation

destination. For the ADDand LACinstructions, the data

to be accumulated or loaded can be optionally scaled

through the barrel shifter prior to accumulation.

The OA and OB bits are modified each time data

passes through the adder/subtracter. When set, they

indicate that the most recent operation has overflowed

into the accumulator guard bits (bits 32 through 39).

The OA and OB bits can also optionally generate an

arithmetic warning trap when set and the

corresponding overflow trap flag enable bit (OVATE,

OVBTE) in the INTCON1 register (refer to Section 8.0

“Interrupts”) is set. This allows the user to take

The SA and SB bits are modified each time data

passes through the adder/subtracter but can only be

cleared by the user. When set, they indicate that the

accumulator has overflowed its maximum range (bit 31

for 32-bit saturation or bit 39 for 40-bit saturation) and

will be saturated if saturation is enabled. When satura-

tion is not enabled, SA and SB default to bit 39 overflow

and thus indicate that a catastrophic overflow has

occurred. If the COVTE bit in the INTCON1 register is

set, SA and SB bits generate an arithmetic warning trap

when saturation is disabled.

2.4.2.2

Accumulator ‘Write-Back’

The MAC class of instructions (with the exception of

MPY, MPY.N, ED and EDAC) can optionally write a

rounded version of the high word (bits 31 through 16)

of the accumulator that is not targeted by the instruction

into data space memory. The write is performed across

the X bus into combined X and Y address space. The

following addressing modes are supported:

1. W13, Register Direct:

The rounded contents of the non-target

accumulator are written into W13 as a 1.15

fraction.

The overflow and saturation Status bits can optionally

be viewed in the STATUS register (SR) as the logical

OR of OA and OB (in bit OAB) and the logical OR of SA

and SB (in bit SAB). This allows programmers to check

one bit in the STATUS register to determine if either

accumulator has overflowed, or one bit to determine if

either accumulator has saturated. This would be useful

for complex number arithmetic which typically uses

both the accumulators.

2. [W13]+

=

2,

Register

Indirect

with

Post-Increment:

The rounded contents of the non-target

accumulator are written into the address pointed

to by W13 as a 1.15 fraction. W13 is then

incremented by 2 (for a word write).

2.4.2.3

Round Logic

The device supports three saturation and overflow

modes:

The round logic is a combinational block which

performs

a conventional (biased) or convergent

1. Bit 39 Overflow and Saturation:

(unbiased) round function during an accumulator write

(store). The Round mode is determined by the state of

the RND bit in the CORCON register. It generates a

16-bit, 1.15 data value, which is passed to the data

space write saturation logic. If rounding is not indicated

by the instruction, a truncated 1.15 data value is stored

and the least significant word (lsw) is simply discarded.

When bit 39 overflow and saturation occurs, the

saturation logic loads the maximally positive 9.31

(0x7FFFFFFFFF) or maximally negative 9.31

value

(0x8000000000)

into the target

accumulator. The SA or SB bit is set and remains

set until cleared by the user. This is referred to as

‘super saturation’ and provides protection against

erroneous data or unexpected algorithm

problems (e.g., gain calculations).

Conventional rounding takes bit 15 of the accumulator,

zero-extends it and adds it to the ACCxH word (bits 16

through 31 of the accumulator). If the ACCxL word

(bits 0 through 15 of the accumulator) is between

0x8000 and 0xFFFF (0x8000 included), ACCxH is

incremented. If ACCxL is between 0x0000 and 0x7FFF,

ACCxH is left unchanged. A consequence of this

algorithm is that over a succession of random rounding

operations, the value tends to be biased slightly

positive.

2. Bit 31 Overflow and Saturation:

When bit 31 overflow and saturation occurs, the

saturation logic then loads the maximally posi-

tive 1.31 value (0x007FFFFFFF) or maximally

negative 1.31 value (0x0080000000) into the

target accumulator. The SA or SB bit is set and

remains set until cleared by the user. When this

Saturation mode is in effect, the guard bits are

not used, so the OA, OB or OAB bits are never

set.

Convergent (or unbiased) rounding operates in the

same manner as conventional rounding, except when

ACCxL equals 0x8000. If this is the case, the LSb

(bit 16 of the accumulator) of ACCxH is examined. If it

is ‘1’, ACCxH is incremented. If it is ‘0’, ACCxH is not

modified. Assuming that bit 16 is effectively random in

nature, this scheme will remove any rounding bias that

may accumulate.

3. Bit 39 Catastrophic Overflow:

The bit 39 overflow Status bit from the adder is

used to set the SA or SB bit which remains set

until cleared by the user. No saturation operation

is performed and the accumulator is allowed to

overflow (destroying its sign). If the COVTE bit in

the INTCON1 register is set, a catastrophic

overflow can initiate a trap exception.

The SAC and SAC.R instructions store either a

truncated (SAC) or rounded (SAC.R) version of the

contents of the target accumulator to data memory via

the

X

bus (subject to data saturation, see

Section 2.4.2.4 “Data Space Write Saturation”).

Note that for the MAC class of instructions, the

accumulator write-back operation functions in the

same manner, addressing combined MCU (X and Y)

data space though the X bus. For this class of

instructions, the data is always subject to rounding.

2.4.2.4

Data Space Write Saturation

2.4.3

BARREL SHIFTER

In addition to adder/subtracter saturation, writes to data

space may also be saturated but without affecting the

contents of the source accumulator. The data space

write saturation logic block accepts a 16-bit, 1.15

fractional value from the round logic block as its input,

together with overflow status from the original source

(accumulator) and the 16-bit round adder. These are

combined and used to select the appropriate 1.15

fractional value as output to write to data space

memory.

The barrel shifter is capable of performing up to 16-bit

arithmetic or logic right shifts, or up to 16-bit left shifts

in a single cycle. The source can be either of the two

DSP accumulators, or the X bus (to support multi-bit

shifts of register or memory data).

The shifter requires a signed binary value to determine

both the magnitude (number of bits) and direction of the

shift operation. A positive value shifts the operand right.

A negative value shifts the operand left. A value of ‘0’

does not modify the operand.

If the SATDW bit in the CORCON register is set, data

(after rounding or truncation) is tested for overflow and

adjusted accordingly. For input data greater than

0x007FFF, data written to memory is forced to the

maximum positive 1.15 value, 0x7FFF. For input data

less than 0xFF8000, data written to memory is forced

to the maximum negative 1.15 value, 0x8000. The MSb

of the source (bit 39) is used to determine the sign of

the operand being tested.

The barrel shifter is 40 bits wide, thereby obtaining a

40-bit result for DSP shift operations and a 16-bit result

for MCU shift operations. Data from the X bus is

presented to the barrel shifter between bit positions 16

to 31 for right shifts, and bit positions 0 to 16 for left

shifts.

If the SATDW bit in the CORCON register is not set, the

input data is always passed through unmodified under

all conditions.

Program Address Space

The program address space is 4M instruction words.

The program space memory maps for the

dsPIC30F2011/2012/3012/3013 devices is shown in

Figure 3-1.

Program memory is addressable by a 24-bit value from

either the 23-bit PC, table instruction Effective Address

(EA), or data space EA, when program space is

mapped into data space as defined by Table 3-1. Note

that the program space address is incremented by two

between successive program words in order to provide

compatibility with data space addressing.

User program space access is restricted to the lower

4M instruction word address range (0x000000 to

0x7FFFFE) for all accesses other than TBLRD/TBLWT,

which uses TBLPAG<7> to determine user or configu-

ration space access. In Table 3-1, Program Space

Address Construction, bit 23 allows access to the

Device ID, the User ID and the Configuration bits.

Otherwise, bit 23 is always clear.

A set of table instructions are provided to move byte or

word-sized data to and from program space. See

Figure 3-4 and Figure 3-5.

3.1.1

DATA ACCESS FROM PROGRAM

MEMORY USING TABLE

INSTRUCTIONS

1. TBLRDL:Table Read Low

Word: Read the LS Word of the program address;

P<15:0> maps to D<15:0>.

This architecture fetches 24-bit wide program memory.

Consequently, instructions are always aligned.

However, as the architecture is modified Harvard, data

can also be present in program space.

Byte: Read one of the LSB of the program

address;

There are two methods by which program space can

be accessed: via special table instructions, or through

the remapping of a 16K word program space page into

the upper half of data space (see Section 3.1.2 “Data

Access from Program Memory Using Program

Space Visibility”). The TBLRDL and TBLWTL

instructions offer a direct method of reading or writing

the lsw of any address within program space, without

going through data space. The TBLRDH and TBLWTH

instructions are the only method whereby the upper 8

bits of a program space word can be accessed as data.

P<7:0> maps to the destination byte when byte

select = 0;

P<15:8> maps to the destination byte when byte

select = 1.

2. TBLWTL:Table Write Low (refer to Section 5.0

“Flash Program Memory” for details on Flash

Programming)

3. TBLRDH:Table Read High

Word: Read the MS Word of the program address;

P<23:16> maps to D<7:0>; D<15:8> will always

be = 0.

The PC is incremented by two for each successive

24-bit program word. This allows program memory

addresses to directly map to data space addresses.

Program memory can thus be regarded as two 16-bit

word wide address spaces, residing side by side, each

with the same address range. TBLRDL and TBLWTL

access the space which contains the lsw, and TBLRDH

and TBLWTH access the space which contains the

MSB.

Byte: Read one of the MSB of the program

address;

P<23:16> maps to the destination byte when

byte select = 0;

The destination byte will always be = 0 when

byte select = 1.

4. TBLWTH:Table Write High (refer to Section 5.0

“Flash Program Memory” for details on Flash

Programming)

Figure 3-2 shows how the EA is created for table

operations and data space accesses (PSV = 1). Here,

P<23:0> refers to a program space word, whereas

D<15:0> refers to a data space word.

Note that by incrementing the PC by 2 for each

program memory word, the LS 15 bits of data space

addresses directly map to the LS 15 bits in the

corresponding program space addresses. The

remaining bits are provided by the Program Space

Visibility Page register, PSVPAG<7:0>, as shown in

Figure 3-5.

3.1.2

DATA ACCESS FROM PROGRAM

MEMORY USING PROGRAM SPACE

VISIBILITY

The upper 32 Kbytes of data space may optionally be

mapped into any 16K word program space page. This

provides transparent access of stored constant data

from X data space without the need to use special

instructions (i.e., TBLRDL/H, TBLWTL/Hinstructions).

Note:

PSV access is temporarily disabled during

table reads/writes.

Program space access through the data space occurs

if the MSb of the data space EA is set and program

space visibility is enabled by setting the PSV bit in the

Core Control register (CORCON). The functions of

CORCON are discussed in Section 2.4 “DSP

Engine”.

For instructions that use PSV which are executed

outside a REPEATloop:

• The following instructions require one instruction

cycle in addition to the specified execution time:

- MACclass of instructions with data operand

prefetch

Data accesses to this area add an additional cycle to

the instruction being executed, since two program

memory fetches are required.

- MOVinstructions

- MOV.Dinstructions

Note that the upper half of addressable data space is

always part of the X data space. Therefore, when a

DSP operation uses program space mapping to access

this memory region, Y data space should typically

contain state (variable) data for DSP operations,

• All other instructions require two instruction cycles

in addition to the specified execution time of the

instruction.

For instructions that use PSV which are executed

inside a REPEATloop:

whereas

X data space should typically contain

coefficient (constant) data.

• The following instances require two instruction

cycles in addition to the specified execution time

of the instruction:

Although each data space address, 0x8000 and higher,

maps directly into a corresponding program memory

address (see Figure 3-5), only the lower 16 bits of the

24-bit program word are used to contain the data. The

upper 8 bits should be programmed to force an illegal

instruction to maintain machine robustness. Refer to

the “16-bit MCU and DSC Programmer’s Reference

Manual” (DS70157) for details on instruction encoding.

- Execution in the first iteration

- Execution in the last iteration

- Execution prior to exiting the loop due to an

interrupt

- Execution upon re-entering the loop after an

interrupt is serviced

• Any other iteration of the REPEATloop allow the

instruction accessing data, using PSV, to execute

in a single cycle.

dsPIC30F2011/2012/3012/3013

When executing any instruction other than one of the

MACclass of instructions, the X block consists of the 64

3.2

Data Address Space

The core has two data spaces. The data spaces can be

considered either separate (for some DSP

instructions), or as one unified linear address range (for

MCU instructions). The data spaces are accessed

using two Address Generation Units (AGUs) and

separate data paths.

Kbyte data address space (including all Y addresses).

When executing one of the MAC class of instructions,

the X block consists of the 64 Kbyte data address

space, excluding the Y address block (for data reads

only). In other words, all other instructions regard the

entire data memory as one composite address space.

The MACclass instructions extract the Y address space

from data space and address it using EAs sourced from

W10 and W11. The remaining X data space is

addressed using W8 and W9. Both address spaces are

concurrently accessed only with the MAC class

instructions.

3.2.1

DATA SPACE MEMORY MAP

The data space memory is split into two blocks, X and

Y data space. A key element of this architecture is that

Y space is a subset of X space, and is fully contained

within X space. In order to provide an apparent Linear

Addressing space, X and Y spaces have contiguous

addresses.

The data space memory map for the dsPIC30F2011

and dsPIC30F2012 is shown in Figure 3-6. The data

space memory map for the dsPIC30F3012 and

dsPIC30F3013 is shown in Figure 3-7.

3.2.3

DATA SPACE WIDTH

The X data space is used by all instructions and sup-

ports all addressing modes. There are separate read

and write data buses. The X read data bus is the return

data path for all instructions that view data space as

combined X and Y address space. It is also the X

address space data path for the dual operand read

instructions (MAC class). The X write data bus is the

only write path to data space for all instructions.

The core data width is 16 bits. All internal registers are

organized as 16-bit wide words. Data space memory is

organized in byte addressable, 16-bit wide blocks.

3.2.4

DATA ALIGNMENT

To help maintain backward compatibility with

PIC^®MCU devices and improve data space memory

usage efficiency, the dsPIC30F instruction set supports

both word and byte operations. Data is aligned in data

memory and registers as words, but all data space EAs

resolve to bytes. Data byte reads read the complete

word that contains the byte, using the LSb of any EA to

determine which byte to select. The selected byte is

placed onto the LSB of the X data path (no byte

accesses are possible from the Y data path as the MAC

class of instruction can only fetch words). That is, data

memory and registers are organized as two parallel

byte wide entities with shared (word) address decode

but separate write lines. Data byte writes only write to

the corresponding side of the array or register which

matches the byte address.

The X data space also supports Modulo Addressing for

all instructions, subject to Addressing mode restric-

tions. Bit-Reversed Addressing is only supported for

writes to X data space.

The Y data space is used in concert with the X data

space by the MAC class of instructions (CLR, ED,

EDAC, MAC, MOVSAC, MPY, MPY.N and MSC) to

provide two concurrent data read paths. No writes

occur across the Y bus. This class of instructions

dedicates two W register pointers, W10 and W11, to

always address Y data space, independent of X data

space, whereas W8 and W9 always address X data

space. Note that during accumulator write back, the

data address space is considered a combination of X

and Y data spaces, so the write occurs across the X

bus. Consequently, the write can be to any address in

the entire data space.

As a consequence of this byte accessibility, all Effective

Address calculations (including those generated by the

DSP operations which are restricted to word-sized

data) are internally scaled to step through word-aligned

memory. For example, the core would recognize that

Post-Modified Register Indirect Addressing mode

[Ws++] results in a value of Ws + 1 for byte operations

and Ws + 2 for word operations.

The Y data space can only be used for the data

prefetch operation associated with the MAC class of

instructions. It also supports Modulo Addressing for

automated circular buffers. Of course, all other

instructions can access the Y data address space

through the X data path as part of the composite linear

space.

All word accesses must be aligned to an even address.

Misaligned word data fetches are not supported, so

care should be taken when mixing byte and word

operations, or translating from 8-bit MCU code. Should

a misaligned read or write be attempted, an address

error trap is generated. If the error occurred on a read,

the instruction underway is completed, whereas if it

occurred on a write, the instruction is executed, but the

write does not occur. In either case, a trap is then

executed, allowing the system and/or user to examine

the machine state prior to execution of the address

fault.

The boundary between the X and Y data spaces is

defined as shown in Figure 3-7 and is not user

programmable. Should an EA point to data outside its

own assigned address space, or to a location outside

physical memory, an all zero word/byte is returned. For

example, although Y address space is visible by all

non-MAC instructions using any addressing mode, an

attempt by a MAC instruction to fetch data from that

space using W8 or W9 (X space pointers)

returns 0x0000.

3.2.5

NEAR DATA SPACE

An 8 Kbyte near data space is reserved in X address

memory space between 0x0000 and 0x1FFF, which is

directly addressable via a 13-bit absolute address field

within all memory direct instructions. The remaining X

address space and all of the Y address space is

addressable indirectly. Additionally, the whole of X data

space is addressable using MOV instructions, which

support memory direct addressing with a 16-bit

address field.

There is a Stack Pointer Limit register (SPLIM)

associated with the Stack Pointer. SPLIM is

uninitialized at Reset. As is the case for the Stack

Pointer, SPLIM<0> is forced to ‘0’ because all stack

operations must be word aligned. Whenever an

Effective Address (EA) is generated using W15 as a

source or destination pointer, the address thus

generated is compared with the value in SPLIM. If the

contents of the Stack Pointer (W15) and the SPLIM reg-

ister are equal, and a push operation is performed, a

stack error trap does not occur. The stack error trap

occurs on a subsequent push operation. Thus, for

example, if it is desirable to cause a stack error trap

when the stack grows beyond address 0x2000 in RAM,

initialize the SPLIM with the value, 0x1FFE.

3.2.6

SOFTWARE STACK

The dsPIC DSC devices contain a software stack. W15

is used as the Stack Pointer.

The Stack Pointer always points to the first available

free word and grows from lower addresses towards

higher addresses. It pre-decrements for stack pops

and post-increments for stack pushes, as shown in

Figure 3-10. Note that for a PC push during any CALL

instruction, the MSB of the PC is zero-extended before

the push, ensuring that the MSB is always clear.

Similarly, a Stack Pointer underflow (stack error) trap is

generated when the Stack Pointer address is found to

be less than 0x0800, thus preventing the stack from

interfering with the Special Function Register (SFR)

space.

Note:

A PC push during exception processing

concatenates the SRL register to the MSB

of the PC prior to the push.

A write to the SPLIM register should not be immediately

followed by an indirect read operation using W15.

FILE REGISTER INSTRUCTIONS

4.0

ADDRESS GENERATOR UNITS

Most file register instructions use a 13-bit address field

(f) to directly address data present in the first 8192

bytes of data memory (near data space). Most file

register instructions employ a working register, W0,

which is denoted as WREG in these instructions. The

destination is typically either the same file register or

WREG (with the exception of the MUL instruction),

which writes the result to a register or register pair. The

MOV instruction allows additional flexibility and can

access the entire data space during file register

operation.

Note:

This data sheet summarizes features of

this group of dsPIC30F devices and is not

intended to be a complete reference

source. For more information on the CPU,

(DS70046). For more information on the

(DS70157).

4.1.2

MCU INSTRUCTIONS

The dsPIC DSC core contains two independent

address generator units: the X AGU and Y AGU. The Y

AGU supports word-sized data reads for the DSP MAC

class of instructions only. The dsPIC DSC AGUs

support three types of data addressing:

The three-operand MCU instructions are of the form:

Operand 3 = Operand 1 <function> Operand 2

where Operand 1 is always a working register (i.e., the

addressing mode can only be register direct), which is

referred to as Wb. Operand 2 can be a W register,

fetched from data memory or a 5-bit literal. The result

location can be either a W register or an address

location. The following addressing modes are

supported by MCU instructions:

• Linear Addressing

• Modulo (Circular) Addressing

• Bit-Reversed Addressing

Linear and Modulo Data Addressing modes can be

applied to data space or program space. Bit-Reversed

Addressing is only applicable to data space addresses.

• Register Direct

• Register Indirect

• Register Indirect Post-modified

• Register Indirect Pre-modified

• 5-bit or 10-bit Literal

4.1

Instruction Addressing Modes

The addressing modes in Table 4-1 form the basis of

the addressing modes optimized to support the specific

features of individual instructions. The addressing

modes provided in the MAC class of instructions are

somewhat different from those in the other instruction

types.

Note:

Not all instructions support all the

addressing modes given above. Individual

instructions may support different subsets

of these addressing modes.

TABLE 4-1:

FUNDAMENTAL ADDRESSING MODES SUPPORTED

Description

The address of the File register is specified explicitly.

File Register Direct

Register Direct

The contents of a register are accessed directly.

Register Indirect

Register Indirect Post-modified

The contents of Wn forms the EA. Wn is post-modified (incremented or

decremented) by a constant value.

Register Indirect Pre-modified

Wn is pre-modified (incremented or decremented) by a signed constant value

to form the EA.

Register Indirect with Register Offset The sum of Wn and Wb forms the EA.

Register Indirect with Literal Offset

The sum of Wn and a literal forms the EA.

DS70139G-page 43

dsPIC30F2011/2012/3012/3013

In summary, the following addressing modes are

supported by the MACclass of instructions:

4.1.3

MOVE AND ACCUMULATOR

INSTRUCTIONS

• Register Indirect

Move instructions and the DSP accumulator class of

instructions provide a greater degree of addressing

flexibility than other instructions. In addition to the

addressing modes supported by most MCU

instructions, move and accumulator instructions also

support Register Indirect with Register Offset

Addressing mode, also referred to as Register Indexed

mode.

• Register Indirect Post-modified by 2

• Register Indirect Post-modified by 4

• Register Indirect Post-modified by 6

• Register Indirect with Register Offset (Indexed)

4.1.5

OTHER INSTRUCTIONS

Besides the various addressing modes outlined above,

some instructions use literal constants of various sizes.

For example, BRA (branch) instructions use 16-bit

signed literals to specify the branch destination directly,

whereas the DISI instruction uses a 14-bit unsigned

literal field. In some instructions, such as ADD Acc, the

source of an operand or result is implied by the opcode

itself. Certain operations, such as NOP, do not have any

operands.

Note:

For the MOV instructions, the addressing

mode specified in the instruction can differ

for the source and destination EA.

However, the 4-bit Wb (register offset)

field is shared between both source and

destination (but typically only used by

one).

In summary, the following addressing modes are

supported by move and accumulator instructions:

4.2

Modulo Addressing

• Register Direct

• Register Indirect

Modulo Addressing is a method of providing an

automated means to support circular data buffers using

hardware. The objective is to remove the need for

software to perform data address boundary checks

when executing tightly looped code, as is typical in

many DSP algorithms.

• Register Indirect Post-modified

• Register Indirect Pre-modified

• Register Indirect with Register Offset (Indexed)

• Register Indirect with Literal Offset

• 8-bit Literal

Modulo Addressing can operate in either data or

program space (since the data pointer mechanism is

essentially the same for both). One circular buffer can

be supported in each of the X (which also provides the

pointers into program space) and Y data spaces.

Modulo Addressing can operate on any W register

pointer. However, it is not advisable to use W14 or W15

for Modulo Addressing since these two registers are

used as the Stack Frame Pointer and Stack Pointer,

respectively.

• 16-bit Literal

Note:

Not all instructions support all the

addressing modes given above. Individual

instructions may support different subsets

of these addressing modes.

4.1.4

MACINSTRUCTIONS

The dual source operand DSP instructions (CLR, ED,

EDAC, MAC, MPY, MPY.N, MOVSACand MSC), also

referred to as MACinstructions, utilize a simplified set of

addressing modes to allow the user to effectively

manipulate the data pointers through register indirect

tables.

In general, any particular circular buffer can only be

configured to operate in one direction, as there are

certain restrictions on the buffer Start address

(for incrementing

buffers),

or

end

address

The two source operand prefetch registers must belong

to the set {W8, W9, W10, W11}. For data reads, W8

and W9 are always directed to the X RAGU. W10 and

W11 are always directed to the Y AGU. The effective

addresses generated (before and after modification)

must, therefore, be valid addresses within X data space

for W8 and W9 and Y data space for W10 and W11.

(for decrementing buffers) based upon the direction of

the buffer.

The only exception to the usage restrictions is for

buffers that have a power-of-2 length. As these buffers

satisfy the Start and the end address criteria, they can

operate in a Bidirectional mode (i.e., address boundary

checks are performed on both the lower and upper

address boundaries).

Note:

Register Indirect with Register Offset

addressing is only available for W9 (in X

space) and W11 (in Y space).

4.2.1

START AND END ADDRESS

4.2.2

W ADDRESS REGISTER

SELECTION

The Modulo Addressing scheme requires that a

starting and an ending address be specified and loaded

into the 16-bit Modulo Buffer Address registers:

XMODSRT, XMODEND, YMODSRT and YMODEND

(see Table 3-3).

The Modulo and Bit-Reversed Addressing Control

register, MODCON<15:0>, contains enable flags as

well as a W register field to specify the W address

registers. The XWM and YWM fields select which

registers

If XWM = 15,

operate

with

Modulo

Addressing.

Note:

Y

space Modulo Addressing EA

X

RAGU and

X

WAGU Modulo

calculations assume word-sized data

(LSb of every EA is always clear).

Addressing is disabled. Similarly, if YWM = 15, Y AGU

Modulo Addressing is disabled.

The length of a circular buffer is not directly specified. It

is determined by the difference between the

corresponding Start and end addresses. The maximum

possible length of the circular buffer is 32K words

(64 Kbytes).

The X Address Space Pointer W register (XWM), to

which Modulo Addressing is to be applied, is stored in

MODCON<3:0> (see Table 3-3). Modulo Addressing is

enabled for X data space when XWM is set to any value

other than ‘15’ and the XMODEN bit is set at

MODCON<15>.

The Y Address Space Pointer W register (YWM), to

which Modulo Addressing is to be applied, is stored in

MODCON<7:4>. Modulo Addressing is enabled for Y

data space when YWM is set to any value other

than ‘15’ and the YMODEN bit is set at

MODCON<14>.

If the length of a bit-reversed buffer is M = 2^Nbytes,

then the last ‘N’ bits of the data buffer Start address

must be zeros.

4.2.3

MODULO ADDRESSING

APPLICABILITY

Modulo Addressing can be applied to the Effective

Address (EA) calculation associated with any W

register. It is important to realize that the address

boundaries check for addresses less than, or greater

than the upper (for incrementing buffers), and lower (for

decrementing buffers) boundary addresses (not just

equal to). Address changes may, therefore, jump

beyond boundaries and still be adjusted correctly.

XB<14:0> is the bit-reversed address modifier or ‘pivot

point’ which is typically a constant. In the case of an

FFT computation, its value is equal to half of the FFT

data buffer size.

Note:

All bit-reversed EA calculations assume

word-sized data (LSb of every EA is

always clear). The XB value is scaled

accordingly to generate compatible (byte)

addresses.

Note:

The modulo corrected Effective Address

is written back to the register only when

Pre-Modify or Post-Modify Addressing

mode is used to compute the EA. When

an address offset (e.g., [W7+W2]) is used,

Modulo address correction is performed,

but the contents of the register remain

unchanged.

When enabled, Bit-Reversed Addressing is only

executed for register indirect with pre-increment or

post-increment addressing and word-sized data writes.

It does not function for any other addressing mode or

for byte-sized data. Normal addresses are generated

instead. When Bit-Reversed Addressing is active, the

W address pointer is always added to the address

modifier (XB) and the offset associated with the

Register Indirect Addressing mode is ignored. In

addition, as word-sized data is a requirement, the LSb

of the EA is ignored (and always clear).

4.3

Bit-Reversed Addressing

Bit-Reversed Addressing is intended to simplify data

re-ordering for radix-2 FFT algorithms. It is supported

by the X AGU for data writes only.

Note:

Modulo Addressing and Bit-Reversed

Addressing should not be enabled

together. In the event that the user

attempts to do this, Bit-Reversed Address-

ing assumes priority when active for the X

WAGU, and X WAGU Modulo Addressing

is disabled. However, Modulo Addressing

continues to function in the X RAGU.

The modifier, which may be a constant value or register

contents, is regarded as having its bit order reversed. The

address source and destination are kept in normal order.

Thus, the only operand requiring reversal is the modifier.

4.3.1

BIT-REVERSED ADDRESSING

IMPLEMENTATION

Bit-Reversed Addressing is enabled when:

If Bit-Reversed Addressing has already been enabled

by setting the BREN bit (XBREV<15>), then a write to

the XBREV register should not be immediately followed

by an indirect read operation using the W register that

has been designated as the bit-reversed pointer.

• BWM (W register selection) in the MODCON reg-

ister is any value other than ‘15’ (the stack cannot

be accessed using Bit-Reversed Addressing)

and

• The BREN bit is set in the XBREV register

and

• The addressing mode used is Register Indirect

with Pre-Increment or Post-Increment.

In-Circuit Serial Programming

(ICSP)

dsPIC30F devices can be serially programmed while in

the end application circuit. This is simply done with two

lines for Programming Clock and Programming Data

(which are named PGC and PGD respectively), and

three other lines for Power (VDD), Ground (VSS) and

Master Clear (MCLR). This allows customers to

manufacture boards with unprogrammed devices, and

then program the microcontroller just before shipping

the product. This also allows the most recent firmware

or a custom firmware to be programmed.

RTSP Operation

5.5

Control Registers

The dsPIC30F Flash program memory is organized

into rows and panels. Each row consists of 32

instructions or 96 bytes. Each panel consists of 128

rows or 4K x 24 instructions. RTSP allows the user to

erase one row (32 instructions) at a time and to

program four instructions at one time. RTSP may be

used to program multiple program memory panels, but

the table pointer must be changed at each panel

boundary.

The four SFRs used to read and write the program

Flash memory are:

• NVMCON

• NVMADR

• NVMADRU

• NVMKEY

5.5.1

NVMCON REGISTER

The NVMCON register controls which blocks are to be

erased, which memory type is to be programmed, and

start of the programming cycle.

Each panel of program memory contains write latches

that hold 32 instructions of programming data. Prior to

the actual programming operation, the write data must

be loaded into the panel write latches. The data to be

programmed into the panel is loaded in sequential

order into the write latches; instruction 0, instruction 1,

etc. The instruction words loaded must always be from

a 32 address boundary.

5.5.2

NVMADR REGISTER

The NVMADR register is used to hold the lower two

bytes of the Effective Address. The NVMADR register

captures the EA<15:0> of the last table instruction that

has been executed and selects the row to write.

The basic sequence for RTSP programming is to set up

a Table Pointer, then do a series of TBLWTinstructions

to load the write latches. Programming is performed by

setting the special bits in the NVMCON register. 32

TBLWTL and four TBLWTH instructions are required to

load the 32 instructions. If multiple panel programming

is required, the Table Pointer needs to be changed and

the next set of multiple write latches written.

5.5.3

NVMADRU REGISTER

The NVMADRU register is used to hold the upper byte

of the Effective Address. The NVMADRU register

captures the EA<23:16> of the last table instruction

that has been executed.

5.5.4

NVMKEY REGISTER

All of the table write operations are single-word writes

(2 instruction cycles), because only the table latches

are written. A programming cycle is required for

programming each row.

NVMKEY is a write-only register that is used for write

protection. To start a programming or an erase

sequence, the user must consecutively write 0x55 and

0xAA to the NVMKEY register. Refer to Section 5.6

“Programming Operations” for further details.

The Flash Program Memory is readable, writable and

erasable during normal operation over the entire VDD

range.

Note:

The user can also directly write to the

NVMADR and NVMADRU registers to

specify a program memory address for

erasing or programming.

4. Write 32 instruction words of data from data

5.6

Programming Operations

RAM “image” into the program Flash write

latches.

A complete programming sequence is necessary for

programming or erasing the internal Flash in RTSP

mode. A programming operation is nominally 2 msec in

duration and the processor stalls (waits) until the

operation is finished. Setting the WR bit

(NVMCON<15>) starts the operation and the WR bit is

automatically cleared when the operation is finished.

5. Program 32 instruction words into program

Flash.

a) Set up NVMCON register for multi-word,

program Flash, program, and set WREN

bit.

b) Write 0x55 to NVMKEY.

5.6.1

PROGRAMMING ALGORITHM FOR

PROGRAM FLASH

c) Write 0xAA to NVMKEY.

d) Set the WR bit. This begins program cycle.

e) CPU stalls for duration of the program cycle.

The user can erase or program one row of program

Flash memory at a time. The general process is:

f) The WR bit is cleared by the hardware

when program cycle ends.

1. Read one row of program Flash (32 instruction

words) and store into data RAM as a data

“image”.

6. Repeat steps 1 through 5 as needed to program

desired amount of program Flash memory.

2. Update the data image with the desired new

data.

5.6.2

ERASING A ROW OF PROGRAM

MEMORY

3. Erase program Flash row.

Example 5-1 shows a code sequence that can be used

to erase a row (32 instructions) of program memory.

a) Set up NVMCON register for multi-word,

program Flash, erase, and set WREN bit.

b) Write address of row to be erased into

NVMADRU/NVMDR.

c) Write 0x55 to NVMKEY.

d) Write 0xAA to NVMKEY.

e) Set the WR bit. This begins erase cycle.

f) CPU stalls for the duration of the erase cycle.

g) The WR bit is cleared when erase cycle

ends.

must be used to allow any erase or program operation

to proceed. After the programming command has been

executed, the user must wait for the programming time

until programming is complete. The two instructions

should be NOPs as shown in Example 5-3.

does not stop the instruction flow. The user is

responsible for waiting for the appropriate duration of

time before initiating another data EEPROM write/

erase operation. Attempting to read the data EEPROM

while a programming or erase operation is in progress

results in unspecified data.

The WREN bit, when set, allows a write operation. On

power-up, the WREN bit is clear. The WRERR bit is set

when a write operation is interrupted by a MCLR Reset

or a WDT Time-out Reset during normal operation. In

these situations, following Reset, the user can check

the WRERR bit and rewrite the location. The address

register NVMADR remains unchanged.

The data EEPROM memory is readable and writable

during normal operation over the entire VDD range. The

data EEPROM memory is directly mapped in the

program memory address space.

The four SFRs used to read and write the program

Flash memory are used to access data EEPROM

memory, as well. As described in Section 5.5 “Control

Registers”, these registers are:

Reading the Data EEPROM

A TBLRD instruction reads a word at the current

program word address. This example uses W0 as a

pointer to data EEPROM. The result is placed in

register W4 as shown in Example 6-1.

The EEPROM data memory allows read and write of

single words and 16-word blocks. When interfacing to

data memory, NVMADR, in conjunction with the

NVMADRU register, are used to address the

EEPROM location being accessed. TBLRDL and

TBLWTLinstructions are used to read and write data

EEPROM. The dsPIC30F devices have up to 8 Kbytes

(4K words) of data EEPROM with an address range

from 0x7FF000 to 0x7FFFFE.

A word write operation should be preceded by an erase

of the corresponding memory location(s). The write

typically requires 2 ms to complete, but the write time

varies with voltage and temperature.

Erasing Data EEPROM

6.2.1

ERASING A BLOCK OF DATA

EEPROM

In order to erase a block of data EEPROM, the

NVMADRU and NVMADR registers must initially point

to the block of memory to be erased. Configure

NVMCON for erasing a block of data EEPROM and

set the WR and WREN bits in the NVMCON register.

Setting the WR bit initiates the erase, as shown in

Example 6-2.

The write does not initiate if the above sequence is not

6.3

Writing to the Data EEPROM

exactly followed (write 0x55 to NVMKEY, write 0xAA to

NVMCON, then set WR bit) for each word. It is strongly

recommended that interrupts be disabled during this

code segment.

To write an EEPROM data location, the following

sequence must be followed:

1. Erase data EEPROM word.

a) Select word, data EEPROM erase, and set

WREN bit in NVMCON register.

Additionally, the WREN bit in NVMCON must be set to

enable writes. This mechanism prevents accidental

writes to data EEPROM due to unexpected code

execution. The WREN bit should be kept clear at all

times except when updating the EEPROM. The WREN

bit is not cleared by hardware.

b) Write address of word to be erased into

NVMADR.

c) Enable NVM interrupt (optional).

d) Write 0x55 to NVMKEY.

After a write sequence has been initiated, clearing the

WREN bit does not affect the current write cycle. The

WR bit is inhibited from being set unless the WREN bit

is set. The WREN bit must be set on a previous

instruction. Both WR and WREN cannot be set with the

same instruction.

e) Write 0xAA to NVMKEY.

f) Set the WR bit. This begins erase cycle.

g) Either poll NVMIF bit or wait for NVMIF

interrupt.

h) The WR bit is cleared when the erase cycle

ends.

At the completion of the write cycle, the WR bit is

cleared in hardware and the Nonvolatile Memory Write

Complete Interrupt Flag bit (NVMIF) is set. The user

may either enable this interrupt or poll this bit. NVMIF

must be cleared by software.

2. Write data word into data EEPROM write

latches.

3. Program 1 data word into data EEPROM.

a) Select word, data EEPROM program, and

set WREN bit in NVMCON register.

6.3.1

WRITING A WORD OF DATA

EEPROM

b) Enable NVM write done interrupt (optional).

c) Write 0x55 to NVMKEY.

Once the user has erased the word to be programmed,

then a table write instruction is used to write one write

latch, as shown in Example 6-4.

d) Write 0xAA to NVMKEY.

e) Set the WR bit. This begins program cycle.

f) Either poll NVMIF bit or wait for NVM

interrupt.

6.3.2

WRITING A BLOCK OF DATA

EEPROM

g) The WR bit is cleared when the write cycle

ends.

To write a block of data EEPROM, write to all sixteen

latches first, then set the NVMCON register and

program the block.

Write Verify

6.5

Protection Against Spurious Write

Depending on the application, good programming

practice may dictate that the value written to the mem-

ory should be verified against the original value. This

should be used in applications where excessive writes

can stress bits near the specification limit.

There are conditions when the device may not want to

write to the data EEPROM memory. To protect against

spurious EEPROM writes, various mechanisms have

been built-in. On power-up, the WREN bit is cleared;

also, the Power-up Timer prevents EEPROM write.

The write initiate sequence and the WREN bit together

help prevent an accidental write during brown-out,

power glitch, or software malfunction.

port pins, write the latch (LATx).

Any bit and its associated data and Control registers

that are not valid for a particular device are disabled.

That means the corresponding LATx and TRISx

registers and the port pin read as zeros.

When a pin is shared with another peripheral or

function that is defined as an input only, it is

nevertheless regarded as a dedicated port because

there is no other competing source of outputs.

All of the device pins (except VDD, VSS, MCLR and

OSC1/CLKI) are shared between the peripherals and

the parallel I/O ports.

A parallel I/O (PIO) port that shares a pin with a

peripheral is, in general, subservient to the peripheral.

The peripheral’s output buffer data and control signals

are provided to a pair of multiplexers. The multiplexers

select whether the peripheral or the associated port

has ownership of the output data and control signals of

the I/O pad cell. Figure 7-1 illustrates how ports are

shared with other peripherals and the associated I/O

cell (pad) to which they are connected.

All I/O input ports feature Schmitt Trigger inputs for

improved noise immunity.

7.1

Parallel I/O (PIO) Ports

When a peripheral is enabled and the peripheral is

actively driving an associated pin, the use of the pin as

a general purpose output pin is disabled. The I/O pin

can be read, but the output driver for the parallel port bit

is disabled. If a peripheral is enabled, but the peripheral

is not actively driving a pin, that pin can be driven by a

port.

The format of the registers for the shared ports,

(PORTB, PORTC, PORTD and PORTF) are shown in

Table 7-1 through Table 7-6.

Note:

The actual bits in use vary between

devices.

All port pins have three registers directly associated

with the operation of the port pin. The Data Direction

register (TRISx) determines whether the pin is an input

or an output. If the data direction bit is a ‘1’, then the pin

is an input. All port pins are defined as inputs after a

Reset. Reads from the latch (LATx), read the latch.

7.2

Configuring Analog Port Pins

One instruction cycle is required between a port

direction change or port write operation and a read

operation of the same port. Typically this instruction

would be a NOP.

The use of the ADPCFG and TRIS registers control the

operation of the A/D port pins. The port pins that are

desired as analog inputs must have their

corresponding TRIS bit set (input). If the TRIS bit is

cleared (output), the digital output level (VOH or VOL) is

converted.

EXAMPLE 7-1:

PORT WRITE/READ

EXAMPLE

When the PORT register is read, all pins configured as

analog input channels are read as cleared (a low level).

MOV #0xF0, W0 ; Configure PORTB<7:4>

; as inputs

MOV W0, TRISB ; and PORTB<3:0> as outputs

Pins configured as digital inputs will not convert an

analog input. Analog levels on any pin that is defined as

a digital input (including the ANx pins) may cause the

input buffer to consume the current that exceeds

device specifications.

Input Change Notification Module

The input change notification module provides the

dsPIC30F devices the ability to generate interrupt

requests to the processor, in response to a change of

state on selected input pins. This module is capable of

detecting input change of states even in Sleep mode,

when the clocks are disabled. There are up to 10

external signals (CN0 through CN7, CN17 and CN18)

that may be selected (enabled) for generating an

interrupt request on a change of state.

Programmer’s

Reference

Manual”

(DS70157).

All interrupt sources can be user assigned to one of 7

priority levels, 1 through 7, through the IPCx registers.

Each interrupt source is associated with an interrupt

vector, as shown in Table 8-1. Levels 7 and 1 represent

the highest and lowest maskable priorities, respec-

tively.

The dsPIC30F sensor family has up to 21 interrupt

sources and 4 processor exceptions (traps) which must

be arbitrated based on a priority scheme.

The CPU is responsible for reading the Interrupt Vector

Table (IVT) and transferring the address contained in

the interrupt vector to the program counter. The

interrupt vector is transferred from the program data

bus into the program counter via a 24-bit wide

multiplexer on the input of the program counter.

Note:

Assigning a priority level of ‘0’ to an

interrupt source is equivalent to disabling

that interrupt.

If the NSTDIS bit (INTCON1<15>) is set, nesting of

interrupts is prevented. Thus, if an interrupt is currently

being serviced, processing of a new interrupt is

prevented even if the new interrupt is of higher priority

than the one currently being serviced.

The Interrupt Vector Table (IVT) and Alternate Interrupt

Vector Table (AIVT) are placed near the beginning of

program memory (0x000004). The IVT and AIVT are

shown in Figure 8-1.

The interrupt controller

is

for

Note:

The IPL bits become read-only whenever

pre-processing the interrupts and processor

exceptions before they are presented to the processor

core. The peripheral interrupts and traps are enabled,

prioritized and controlled using centralized Special

Function Registers (SFRs):

the NSTDIS bit has been set to ‘1’.

Certain interrupts have specialized control bits for

features like edge or level triggered interrupts,

interrupt-on-change, etc. Control of these features

remains within the peripheral module which generates

the interrupt.

• IFS0<15:0>, IFS1<15:0>, IFS2<15:0>

All interrupt request flags are maintained in these

three registers. The flags are set by their

respective peripherals or external signals and

they are cleared via software.

The DISI instruction can be used to disable the

processing of interrupts of priorities 6 and lower for a

certain number of instructions, during which the DISI bit

(INTCON2<14>) remains set.

• IEC0<15:0>, IEC1<15:0>, IEC2<15:0>

All interrupt enable control bits are maintained in

these three registers. These control bits are used

to individually enable interrupts from the

peripherals or external signals.

When an interrupt is serviced, the PC is loaded with the

address stored in the vector location in program

memory that corresponds to the interrupt. There are 63

different vectors within the IVT (refer to Table 8-1).

These vectors are contained in locations 0x000004

through 0x0000FE of program memory (refer to

Table 8-1). These locations contain 24-bit addresses,

and in order to preserve robustness, an address error

trap takes place if the PC attempts to fetch any of these

words during normal execution. This prevents

execution of random data as a result of accidentally

decrementing a PC into vector space, accidentally

mapping a data space address into vector space, or the

PC rolling over to 0x000000 after reaching the end of

implemented program memory space. Execution of a

GOTOinstruction to this vector space also generates an

address error trap.

• IPC0<15:0> through IPC10<7:0>

The user assignable priority level associated with

each of these 41 interrupts is held centrally in

these eleven registers.

• IPL<3:0>

The current CPU priority level is explicitly stored

in the IPL bits. IPL<3> is present in the CORCON

register, whereas IPL<2:0> are present in the

STATUS register (SR) in the processor core.

The ability for the user to assign every interrupt to one

of seven priority levels means that the user can assign

a very high overall priority level to an interrupt with a

low natural order priority. For example, the PLVD

(Low Voltage Detect) can be given a priority of 7. The

INT0 (External Interrupt 0) may be assigned to priority

level 1, thus giving it a very low effective priority.

8.2

Reset Sequence

8.3

Traps

A Reset is not a true exception because the interrupt

controller is not involved in the Reset process. The

processor initializes its registers in response to a Reset

which forces the PC to zero. The processor then begins

program execution at location 0x000000. A GOTO

instruction is stored in the first program memory

location immediately followed by the address target for

the GOTOinstruction. The processor executes the GOTO

to the specified address and then begins operation at

the specified target (start) address.

Traps can be considered as non-maskable interrupts

indicating a software or hardware error, which adhere

to a predefined priority as shown in Figure 8-1. They

are intended to provide the user a means to correct

erroneous operation during debug and when operating

within the application.

Note:

If the user does not intend to take

corrective action in the event of a trap

error condition, these vectors must be

loaded with the address of a default

handler that contains the RESET instruc-

tion. If, on the other hand, one of the vec-

tors containing an invalid address is

called, an address error trap is generated.

8.2.1

RESET SOURCES

In addition to external Reset and Power-on Reset

(POR), there are six sources of error conditions which

‘trap’ to the Reset vector.

Note that many of these trap conditions can only be

detected when they occur. Consequently, the

questionable instruction is allowed to complete prior to

trap exception processing. If the user chooses to

recover from the error, the result of the erroneous

action that caused the trap may have to be corrected.

• Watchdog Time-out:

The watchdog has timed out, indicating that the

processor is no longer executing the correct flow

of code.

• Uninitialized W Register Trap:

An attempt to use an uninitialized W register as

an Address Pointer causes a Reset.

There are eight fixed priority levels for traps: Level 8

through Level 15, which implies that the IPL3 is always

set during processing of a trap.

• Illegal Instruction Trap:

Attempted execution of any unused opcodes

results in an illegal instruction trap. Note that a

fetch of an illegal instruction does not result in an

illegal instruction trap if that instruction is flushed

prior to execution due to a flow change.

If the user is not currently executing a trap, and he sets

the IPL<3:0> bits to a value of ‘0111’ (Level 7), then all

interrupts are disabled, but traps can still be processed.

8.3.1

TRAP SOURCES

• Brown-out Reset (BOR):

The following traps are provided with increasing

priority. However, since all traps can be nested, priority

has little effect.

A momentary dip in the power supply to the

device has been detected which may result in

malfunction.

• Trap Lockout:

Occurrence of multiple trap conditions

simultaneously causes a Reset.

Math Error Trap:

The math error trap executes under the following four

circumstances:

1. If an attempt is made to divide by zero, the

divide operation is aborted on a cycle boundary

and the trap is taken.

2. If enabled, a math error trap is taken when an

arithmetic operation on either accumulator A or

B causes an overflow from bit 31 and the

accumulator guard bits are not utilized.

3. If enabled, a math error trap is taken when an

arithmetic operation on either accumulator A or

B causes a catastrophic overflow from bit 39 and

all saturation is disabled.

4. If the shift amount specified in a shift instruction

is greater than the maximum allowed shift

amount, a trap occurs.

DS70139G-page 67

dsPIC30F2011/2012/3012/3013

Address Error Trap:

Stack Error Trap:

This trap is initiated when any of the following

circumstances occurs:

This trap is initiated under the following conditions:

• The Stack Pointer is loaded with a value which is

greater than the (user programmable) limit value

written into the SPLIM register (stack overflow).

1. A misaligned data word access is attempted.

2. A data fetch from our unimplemented data

memory location is attempted.

• The Stack Pointer is loaded with a value which is

less than 0x0800 (simple stack underflow).

3. A data access of an unimplemented program

memory location is attempted.

Oscillator Fail Trap:

4. An instruction fetch from vector space is

attempted.

This trap is initiated if the external oscillator fails and

operation becomes reliant on an internal RC backup.

Note:

In the MAC class of instructions, wherein

the data space is split into X and Y data

space, unimplemented X space includes

all of Y space, and unimplemented Y

space includes all of X space.

8.3.2

HARD AND SOFT TRAPS

It is possible that multiple traps can become active

within the same cycle (e.g., a misaligned word stack

write to an overflowed address). In such a case, the

fixed priority shown in Figure 8-2 is implemented,

which may require the user to check if other traps are

pending, in order to completely correct the Fault.

5. Execution of a “BRA #literal” instruction or a

“GOTO #literal” instruction, where literal

is an unimplemented program memory address.

6. Executing instructions after modifying the PC to

point the unimplemented program memory

addresses. The PC may be modified by loading

a value into the stack and executing a RETURN

instruction.

Soft traps include exceptions of priority level 8 through

level 11, inclusive. The arithmetic error trap (level 11)

falls into this category of traps.

Hard traps include exceptions of priority level 12

through level 15, inclusive. The address error (level

12), stack error (level 13) and oscillator error (level 14)

traps fall into this category.

Each hard trap that occurs must be acknowledged

before code execution of any type can continue. If a

lower priority hard trap occurs while a higher priority

trap is pending, acknowledged, or is being processed,

a hard trap conflict occurs.

The device is automatically Reset in a hard trap conflict

condition. The TRAPR Status bit (RCON<15>) is set

when the Reset occurs, so that the condition may be

detected in software.

Alternate Vector Table

8.4

Interrupt Sequence

In program memory, the Interrupt Vector Table (IVT) is

followed by the Alternate Interrupt Vector Table (AIVT),

as shown in Figure 8-1. Access to the alternate vector

table is provided by the ALTIVT bit in the INTCON2

register. If the ALTIVT bit is set, all interrupt and

exception processes use the alternate vectors instead

of the default vectors. The alternate vectors are

organized in the same manner as the default vectors.

The AIVT supports emulation and debugging efforts by

providing a means to switch between an application

and a support environment without requiring the

interrupt vectors to be reprogrammed. This feature also

enables switching between applications for evaluation

of different software algorithms at run time.

All interrupt event flags are sampled in the beginning of

each instruction cycle by the IFSx registers. A pending

Interrupt Request (IRQ) is indicated by the flag bit

being equal to a ‘1’ in an IFSx register. The IRQ causes

an interrupt to occur if the corresponding bit in the

Interrupt Enable (IECx) register is set. For the

remainder of the instruction cycle, the priorities of all

pending interrupt requests are evaluated.

If there is a pending IRQ with a priority level greater

than the current processor priority level in the IPL bits,

the processor is interrupted.

The processor then stacks the current program counter

and the low byte of the processor STATUS register

(SRL), as shown in Figure 8-2. The low byte of the

STATUS register contains the processor priority level at

the time prior to the beginning of the interrupt cycle.

The processor then loads the priority level for this

interrupt into the STATUS register. This action disables

all lower priority interrupts until the completion of the

Interrupt Service Routine (ISR).

If the AIVT is not required, the program memory

allocated to the AIVT may be used for other purposes.

AIVT is not a protected section and may be freely

programmed by the user.

Fast Context Saving

8.7

External Interrupt Requests

A context saving option is available using shadow

registers. Shadow registers are provided for the DC, N,

OV, Z and C bits in SR, and the registers W0 through

W3. The shadows are only one level deep. The shadow

registers are accessible using the PUSH.Sand POP.S

instructions only.

The interrupt controller supports three external

interrupt request signals, INT0-INT2. These inputs are

edge sensitive; they require a low-to-high or a

high-to-low transition to generate an interrupt request.

The INTCON2 register has three bits, INT0EP-INT2EP,

that select the polarity of the edge detection circuitry.

When the processor vectors to an interrupt, the

PUSH.S instruction can be used to store the current

value of the aforementioned registers into their

respective shadow registers.

8.8

Wake-up from Sleep and Idle

The interrupt controller may be used to wake-up the

processor from either Sleep or Idle modes, if Sleep or

Idle mode is active when the interrupt is generated.

If an ISR of a certain priority uses the PUSH.S and

POP.S instructions for fast context saving, then a

higher priority ISR should not include the same instruc-

tions. Users must save the key registers in software

during a lower priority interrupt if the higher priority ISR

uses fast context saving.

If an enabled interrupt request of sufficient priority is

received by the interrupt controller, then the standard

interrupt request is presented to the processor. At the

same time, the processor wakes up from Sleep or Idle

and begins execution of the ISR needed to process the

interrupt request.

DS70139G-page 70

This data sheet summarizes features of

this group of dsPIC30F devices and is not

presents a block diagram of the 16-bit timer module.

16-bit Timer Mode: In the 16-bit Timer mode, the timer

increments on every instruction cycle up to a match

value preloaded into the Period register PR1, then

resets to ‘0’ and continues to count.

When the CPU goes into the Idle mode, the timer stops

incrementing unless the TSIDL (T1CON<13>) bit = 0.

If TSIDL = 1, the timer module logic resumes the incre-

menting sequence on termination of CPU Idle mode.

This section describes the 16-bit general purpose

Timer1 module and associated operational modes.

Figure 9-1 depicts the simplified block diagram of the

16-bit Timer1 module. The following sections provide

detailed descriptions including setup and Control

registers, along with associated block diagrams for the

operational modes of the timers.

16-bit Synchronous Counter Mode: In the 16-bit

Synchronous Counter mode, the timer increments on

the rising edge of the applied external clock signal

which is synchronized with the internal phase clocks.

The timer counts up to a match value preloaded in PR1,

then resets to ‘0’ and continues.

The Timer1 module is a 16-bit timer that serves as the

time counter for the real-time clock or operates as a

free-running interval timer/counter. The 16-bit timer has

the following modes:

When the CPU goes into the Idle mode, the timer stops

incrementing unless the respective TSIDL bit = 0. If

TSIDL = 1, the timer module logic resumes the

incrementing sequence upon termination of the CPU

Idle mode.

• 16-bit Timer

• 16-bit Synchronous Counter

• 16-bit Asynchronous Counter

16-bit Asynchronous Counter Mode: In the 16-bit

Asynchronous Counter mode, the timer increments on

every rising edge of the applied external clock signal.

The timer counts up to a match value preloaded in PR1,

then resets to ‘0’ and continues.

These operational characteristics are supported:

• Timer gate operation

• Selectable prescaler settings

• Timer operation during CPU Idle and Sleep

modes

• Interrupt on 16-bit Period register match or falling

edge of external gate signal

When the timer is configured for the Asynchronous

mode of operation and the CPU goes into the Idle

mode, the timer stops incrementing if TSIDL = 1.

When the Gated Time Accumulation mode is enabled,

an interrupt is also generated on the falling edge of the

gate signal (at the end of the accumulation cycle).

9.1

Timer Gate Operation

The 16-bit timer can be placed in the Gated Time

Accumulation mode. This mode allows the internal TCY

to increment the respective timer when the gate input

signal (T1CK pin) is asserted high. Control bit,

TGATE (T1CON<6>), must be set to enable this mode.

The timer must be enabled (TON = 1) and the timer

clock source set to internal (TCS = 0).

Enabling an interrupt is accomplished via the

respective timer interrupt enable bit, T1IE. The timer

interrupt enable bit is located in the IEC0 Control

register in the interrupt controller.

9.5

Real-Time Clock

When the CPU goes into Idle mode, the timer stops

incrementing unless TSIDL = 0. If TSIDL = 1, the timer

resumes the incrementing sequence upon termination

of the CPU Idle mode.

Timer1, when operating in Real-Time Clock (RTC)

mode, provides time of day and event time-stamping

capabilities. Key operational features of the RTC are:

• Operation from 32 kHz LP oscillator

• 8-bit prescaler

9.2

Timer Prescaler

• Low power

• Real-Time Clock interrupts

The input clock (FOSC/4 or external clock) to the 16-bit

Timer has a prescale option of 1:1, 1:8, 1:64 and 1:256,

selected by control bits, TCKPS<1:0> (T1CON<5:4>).

The prescaler counter is cleared when any of the

following occurs:

These operating modes are determined by setting the

appropriate bit(s) in the T1CON register.

• The TSYNC bit (T1CON<2>) is asserted to a logic

‘0’ which defines the external clock source as

asynchronous.

The TSYNC bit must be asserted to a logic ‘0’

(Asynchronous mode) for correct operation.

When all three conditions are true, the timer continues

to count up to the Period register and be reset to

0x0000.

Enabling the LPOSCEN bit (OSCCON<1>) disables

the normal Timer and Counter modes and enables a

timer carry-out wake-up event.

When a match between the timer and the Period

register occurs, an interrupt can be generated if the

respective timer interrupt enable bit is asserted.

When the CPU enters Sleep mode, the RTC continues

to operate, provided the 32 kHz external crystal

oscillator is active and the control bits have not been

changed. The TSIDL bit should be cleared to ‘0’ in

order for RTC to continue operation in Idle mode.

9.4

Timer Interrupt

The 16-bit timer has the ability to generate an

interrupt-on-period match. When the timer count

matches the Period register, the T1IF bit is asserted and

an interrupt is generated, if enabled. The T1IF bit must be

cleared in software. The timer interrupt flag, T1IF, is

located in the IFS0 Control register in the interrupt

controller.

9.5.2

RTC INTERRUPTS

When an interrupt event occurs, the respective interrupt

flag, T1IF, is asserted and an interrupt is generated if

enabled. The T1IF bit must be cleared in software. The

respective Timer interrupt flag, T1IF, is located in the

IFS0 register in the interrupt controller.

this group of dsPIC30F devices and is not

intended to be a complete reference

source. For more information on the CPU,

peripherals, register descriptions and

general device functionality, refer to the

“dsPIC30F Family Reference Manual

“(DS70046).

This section describes the 32-bit general purpose

Timer module (Timer2/3) and associated Operational

modes. Figure 10-1 depicts the simplified block

diagram of the 32-bit Timer2/3 module. Figure 10-2

and Figure 10-3 show Timer2/3 configured as two

independent 16-bit timers, Timer2 and Timer3,

respectively.

16-bit Timer Mode: In the 16-bit mode, Timer2 and

Timer3 can be configured as two independent 16-bit

timers. Each timer can be set up in either 16-bit Timer

mode or 16-bit Synchronous Counter mode. See

Section 9.0 “Timer1 Module” for details on these two

operating modes.

The only functional difference between Timer2 and

Timer3 is that Timer2 provides synchronization of the

clock prescaler output. This is useful for high frequency

external clock inputs.

The Timer2/3 module is a 32-bit timer (which can be

configured as two 16-bit timers) with selectable

operating modes. These timers are utilized by other

peripheral modules, such as:

32-bit Timer Mode: In the 32-bit Timer mode, the timer

increments on every instruction cycle, up to a match

value preloaded into the combined 32-bit Period

register PR3/PR2, then resets to ‘0’ and continues to

count.

• Input Capture

• Output Compare/Simple PWM

The following sections provide a detailed description,

including setup and Control registers, along with

associated block diagrams for the operational modes of

the timers.

For synchronous 32-bit reads of the Timer2/Timer3

pair, reading the ls word (TMR2 register) causes the ms

word to be read and latched into a 16-bit holding

register, termed TMR3HLD.

The 32-bit timer has the following modes:

• Two independent 16-bit timers (Timer2 and

Timer3) with all 16-bit operating modes (except

Asynchronous Counter mode)

For synchronous 32-bit writes, the holding register

(TMR3HLD) must first be written to. When followed by

a write to the TMR2 register, the contents of TMR3HLD

is transferred and latched into the MSB of the 32-bit

timer (TMR3).

• Single 32-bit timer operation

• Single 32-bit synchronous counter

Further, the following operational characteristics are

supported:

32-bit Synchronous Counter Mode: In the 32-bit

Synchronous Counter mode, the timer increments on

the rising edge of the applied external clock signal

which is synchronized with the internal phase clocks.

The timer counts up to a match value preloaded in the

combined 32-bit period register, PR3/PR2, then resets

to ‘0’ and continues.

• ADC event trigger

• Timer gate operation

• Selectable prescaler settings

• Timer operation during Idle and Sleep modes

• Interrupt on a 32-bit period register match

When the timer is configured for the Synchronous

Counter mode of operation and the CPU goes into the

Idle mode, the timer stops incrementing unless the

TSIDL bit (T2CON<13>) = 0. If TSIDL = 1, the timer

module logic resumes the incrementing sequence

upon termination of the CPU Idle mode.

These operating modes are determined by setting the

appropriate bit(s) in the 16-bit T2CON and T3CON

SFRs.

10.1 Timer Gate Operation

10.4 Timer Operation During Sleep

Mode

The 32-bit timer can be placed in the Gated Time

Accumulation mode. This mode allows the internal TCY

to increment the respective timer when the gate input

signal (T2CK pin) is asserted high. Control bit, TGATE

(T2CON<6>), must be set to enable this mode. When

in this mode, Timer2 is the originating clock source.

The TGATE setting is ignored for Timer3. The timer

must be enabled (TON = 1) and the timer clock source

set to internal (TCS = 0).

The timer does not operate during CPU Sleep mode

because the internal clocks are disabled.

10.5 Timer Interrupt

The 32-bit timer module can generate an

interrupt-on-period match or on the falling edge of the

external gate signal. When the 32-bit timer count

matches the respective 32-bit period register, or the

falling edge of the external “gate” signal is detected, the

T3IF bit (IFS0<7>) is asserted and an interrupt is

generated if enabled. In this mode, the T3IF interrupt

flag is used as the source of the interrupt. The T3IF bit

must be cleared in software.

The falling edge of the external signal terminates the

count operation but does not reset the timer. The user

must reset the timer in order to start counting from zero.

10.2 ADC Event Trigger

When a match occurs between the 32-bit timer

(TMR3/TMR2) and the 32-bit combined period register

(PR3/PR2), or between the 16-bit timer TMR3 and the

16-bit period register PR3, a special ADC trigger event

signal is generated by Timer3.

Enabling an interrupt is accomplished via the

respective timer interrupt enable bit, T3IE (IEC0<7>).

10.3 Timer Prescaler

The input clock (FOSC/4 or external clock) to the timer

has a prescale option of 1:1, 1:8, 1:64, and 1:256,

selected by control bits, TCKPS<1:0> (T2CON<5:4>

and T3CON<5:4>). For the 32-bit timer operation, the

originating clock source is Timer2. The prescaler

operation for Timer3 is not applicable in this mode. The

prescaler counter is cleared when any of the following

occurs:

• A write to the TMR2/TMR3 register

• A write to the T2CON/T3CON register

• A device Reset, such as a POR and BOR

However, if the timer is disabled (TON = 0), the Timer

2 prescaler cannot be reset since the prescaler clock is

halted.

TMR2/TMR3 is not cleared when T2CON/T3CON is

written.

The dsPIC30F2011/2012/3012/3013 devices have two

11.1 Simple Capture Event Mode

The simple capture events in the dsPIC30F product

family are:

• Capture every falling edge

• Capture every rising edge

This section describes the input capture module and

associated operational modes. The features provided

by this module are useful in applications requiring

frequency (period) and pulse measurement.

• Capture every 4th rising edge

• Capture every 16th rising edge

• Capture every rising and falling edge

Figure 11-1 depicts a block diagram of the input

capture module. Input capture is useful for such modes

as:

These simple Input Capture modes are configured by

setting the appropriate bits, ICM<2:0> (ICxCON<2:0>).

11.1.1

CAPTURE PRESCALER

• Frequency/Period/Pulse Measurements

• Additional Sources of External Interrupts

There are four input capture prescaler settings

specified by bits ICM<2:0> (ICxCON<2:0>). Whenever

the capture channel is turned off, the prescaler counter

is cleared. In addition, any Reset clears the prescaler

counter.

Important operational features of the input capture

module are:

• Simple Capture Event mode

• Timer2 and Timer3 mode selection

• Interrupt on input capture event

11.1.2

CAPTURE BUFFER OPERATION

11.2 Input Capture Operation During

Sleep and Idle Modes

Each capture channel has an associated FIFO buffer

which is four 16-bit words deep. There are two status

flags which provide status on the FIFO buffer:

An input capture event generates a device wake-up or

interrupt, if enabled, if the device is in CPU Idle or Sleep

mode.

• ICBNE – Input Capture Buffer Not Empty

• ICOV – Input Capture Overflow

Independent of the timer being enabled, the input

capture module wakes up from the CPU Sleep or Idle

mode when a capture event occurs if ICM<2:0> = 111

and the interrupt enable bit is asserted. The same

wake-up can generate an interrupt if the conditions for

processing the interrupt have been satisfied.

The wake-up feature is useful as a method of adding

extra external pin interrupts.

The ICBNE is set on the first input capture event and

remains set until all capture events have been read

from the FIFO. As each word is read from the FIFO, the

remaining words are advanced by one position within

the buffer.

In the event that the FIFO is full with four capture

events, and a fifth capture event occurs prior to a read

of the FIFO, an overflow condition occurs and the ICOV

bit is set to a logic ‘1’. The fifth capture event is lost and

is not stored in the FIFO. No additional events are

captured until all four events have been read from the

buffer.

11.2.1

INPUT CAPTURE IN CPU SLEEP

MODE

CPU Sleep mode allows input capture module

operation with reduced functionality. In the CPU Sleep

mode, the ICI<1:0> bits are not applicable and the input

capture module can only function as an external

interrupt source.

If a FIFO read is performed after the last read and no

new capture event has been received, the read will

yield indeterminate results.

The capture module must be configured for interrupt

only on rising edge (ICM<2:0> = 111) in order for the

input capture module to be used while the device is in

Sleep mode. The prescale settings of 4:1 or 16:1 are

not applicable in this mode.

11.1.3

TIMER2 AND TIMER3 SELECTION

MODE

The input capture module consists of up to 8 input

capture channels. Each channel can select between

one of two timers for the time base, Timer2 or Timer3.

11.2.2

INPUT CAPTURE IN CPU IDLE

MODE

Selection of the timer resource is accomplished

through SFR bit, ICTMR (ICxCON<7>). Timer3 is the

default timer resource available for the input capture

module.

CPU Idle mode allows input capture module operation

with full functionality. In the CPU Idle mode, the Interrupt

mode selected by the ICI<1:0> bits is applicable, as well

as the 4:1 and 16:1 capture prescale settings which are

defined by control bits ICM<2:0>. This mode requires

the selected timer to be enabled. Moreover, the ICSIDL

bit must be asserted to a logic ‘0’.

11.1.4

HALL SENSOR MODE

When the input capture module is set for capture on

every edge, rising and falling, ICM<2:0> = 001, the

following operations are performed by the input capture

logic:

If the input capture module is defined as

ICM<2:0> = 111in CPU Idle mode, the input capture

pin serves only as an external interrupt pin.

• The input capture interrupt flag is set on every

edge, rising and falling.

• The interrupt on Capture mode setting bits,

ICI<1:0>, is ignored since every capture

generates an interrupt.

11.3 Input Capture Interrupts

The input capture channels have the ability to generate

an interrupt based on the selected number of capture

events. The selection number is set by control

bits, ICI<1:0> (ICxCON<6:5>).

• A capture overflow condition is not generated in

this mode.

Each channel provides an interrupt flag (ICxIF) bit. The

respective capture channel interrupt flag is located in

the corresponding IFSx register.

Enabling an interrupt is accomplished via the

respective capture channel interrupt enable (ICxIE) bit.

The capture interrupt enable bit is located in the

corresponding IEC Control register.

• Timer2 and Timer3 Selection mode

• Simple Output Compare Match mode

• Dual Output Compare Match mode

• Simple PWM mode

• Output Compare During Sleep and Idle modes

These operating modes are determined by setting the

appropriate bits in the 16-bit OC1CON and OC2CON

12.3.2

CONTINUOUS PULSE MODE

12.1 Timer2 and Timer3 Selection Mode

For the user to configure the module for the generation

of a continuous stream of output pulses, the following

steps are required:

Each output compare channel can select between one

of two 16-bit timers, Timer2 or Timer3.

The selection of the timers is controlled by the OCTSEL

bit (OCxCON<3>). Timer2 is the default timer resource

for the output compare module.

• Determine instruction cycle time TCY.

• Calculate desired pulse value based on TCY.

• Calculate timer to start pulse width from timer start

value of 0x0000.

12.2 Simple Output Compare Match

Mode

• Write pulse width start and stop times into OCxR

and OCxRS (x denotes channel 1 to N) Compare

registers, respectively.

When control bits OCM<2:0> (OCxCON<2:0>) = 001,

010 or 011, the selected output compare channel is

configured for one of three simple Output Compare

Match modes:

• Set Timer Period register to value equal to or

greater than value in OCxRS Compare register.

• Set OCM<2:0> = 101.

• Compare forces I/O pin low

• Compare forces I/O pin high

• Compare toggles I/O pin

• Enable timer, TON bit (TxCON<15>) = 1.

12.4 Simple PWM Mode

The OCxR register is used in these modes. The OCxR

register is loaded with a value and is compared to the

selected incrementing timer count. When a compare

occurs, one of these Compare Match modes occurs. If

the counter resets to zero before reaching the value in

OCxR, the state of the OCx pin remains unchanged.

When control bits OCM<2:0> (OCxCON<2:0>) = 110

or 111, the selected output compare channel is

configured for the PWM mode of operation. When

configured for the PWM mode of operation, OCxR is

the main latch (read-only) and OCxRS is the secondary

latch. This enables glitchless PWM transitions.

The user must perform the following steps in order to

configure the output compare module for PWM

operation:

12.3 Dual Output Compare Match Mode

When control bits OCM<2:0> (OCxCON<2:0>) = 100

or 101, the selected output compare channel is

configured for one of two Dual Output Compare modes,

which are:

1. Set the PWM period by writing to the appropriate

period register.

2. Set the PWM duty cycle by writing to the OCxRS

register.

• Single Output Pulse mode

• Continuous Output Pulse mode

3. Configure the output compare module for PWM

operation.

12.3.1

SINGLE PULSE MODE

4. Set the TMRx prescale value and enable the

For the user to configure the module for the generation

of a single output pulse, the following steps are

required (assuming timer is off):

Timer, TON bit (TxCON<15>) = 1.

12.4.1

INPUT PIN FAULT PROTECTION

FOR PWM

• Determine instruction cycle time TCY.

• Calculate desired pulse width value based on TCY.

When control bits OCM<2:0> (OCxCON<2:0>) = 111,

the selected output compare channel is again

configured for the PWM mode of operation with the

additional feature of input Fault protection. While in this

mode, if a logic ‘0’ is detected on the OCFA/B pin, the

respective PWM output pin is placed in the high

impedance input state. The OCFLT bit (OCxCON<4>)

indicates whether a Fault condition has occurred. This

state is maintained until both of the following events

have occurred:

• Calculate time to start pulse from timer start value

of 0x0000.

• Write pulse width start and stop times into OCxR

and OCxRS Compare registers (x denotes

channel 1 to N).

• Set Timer Period register to value equal to or

greater than value in OCxRS Compare register.

• Set OCM<2:0> = 100.

• Enable timer, TON bit (TxCON<15>) = 1.

• The external Fault condition has been removed.

To initiate another single pulse, issue another write to

set OCM<2:0> = 100.

• The PWM mode has been re-enabled by writing

to the appropriate control bits.

DS70139G-page 88

dsPIC30F2011/2012/3012/3013

When the selected TMRx is equal to its respective

period register, PRx, the following four events occur on

the next increment cycle:

12.4.2

PWM PERIOD

The PWM period is specified by writing to the PRx

register. The PWM period can be calculated using

Equation 12-1.

• TMRx is cleared.

• The OCx pin is set.

EQUATION 12-1:

- Exception 1: If PWM duty cycle is 0x0000,

the OCx pin remains low.

PWM period = [(PRx) + 1] • 4 • Tosc •

(TMRx prescale value)

- Exception 2: If duty cycle is greater than PRx,

the pin remains high.

• The PWM duty cycle is latched from OCxRS into

OCxR.

PWM frequency is defined as 1/[PWM period].

• The corresponding timer interrupt flag is set.

See Figure 12-2 for key PWM period comparisons.

Timer3 is referred to in Figure 12-2 for clarity.

12.5 Output Compare Operation During

CPU Sleep Mode

12.7 Output Compare Interrupts

The output compare channels have the ability to

generate an interrupt on a compare match, for

whichever Match mode has been selected.

When the CPU enters Sleep mode, all internal clocks

are stopped. Therefore, when the CPU enters the

Sleep state, the output compare channel drives the pin

to the active state that was observed prior to entering

the CPU Sleep state.

For all modes except the PWM mode, when a compare

event occurs, the respective interrupt flag (OCxIF) is

asserted and an interrupt is generated if enabled. The

OCxIF bit is located in the corresponding IFS register

and must be cleared in software. The interrupt is

enabled via the respective compare interrupt enable

(OCxIE) bit located in the corresponding IEC Control

register.

For example, if the pin was high when the CPU entered

the Sleep state, the pin remains high. Likewise, if the

pin was low when the CPU entered the Sleep state, the

pin remains low. In either case, the output compare

module resumes operation when the device wakes up.

For the PWM mode, when an event occurs, the

respective timer interrupt flag (T2IF or T3IF) is asserted

and an interrupt is generated if enabled. The IF bit is

located in the IFS0 register and must be cleared in

software. The interrupt is enabled via the respective

timer interrupt enable bit (T2IE or T3IE) located in the

IEC0 Control register. The output compare interrupt

flag is never set during the PWM mode of operation.

12.6 Output Compare Operation During

CPU Idle Mode

When the CPU enters the Idle mode, the output

compare module can operate with full functionality.

The output compare channel operates during the CPU

Idle mode if the OCSIDL bit (OCxCON<13>) is at logic

‘0’ and the selected time base (Timer2 or Timer3) is

enabled and the TSIDL bit of the selected timer is set

to logic ‘0’.

13.0 SPI™ MODULE

Note:

This data sheet summarizes features of

this group of dsPIC30F devices and is not

A series of eight (8) or sixteen (16) clock pulses shift

out bits from the SPI1SR to SDO1 pin and

simultaneously shift in data from SDI1 pin. An interrupt

is generated when the transfer is complete and the

interrupt flag bit (SPI1IF) is set. This interrupt can be

disabled through the interrupt enable bit, SPI1IE.

intended to be a complete reference

source. For more information on the CPU,

peripherals, register descriptions and

general device functionality, refer to the

“dsPIC30F Family Reference Manual”

(DS70046).

The receive operation is double-buffered. When a

complete byte is received, it is transferred from SPI1SR

to SPI1BUF.

The Serial Peripheral Interface (SPI™) module is a

synchronous serial interface. It is useful for

communicating with other peripheral devices, such as

EEPROMs, shift registers, display drivers and A/D

converters, or other microcontrollers. It is compatible

with Motorola's SPI and SIOP interfaces. The

dsPIC30F2011/2012/3012/3013 devices feature one

SPI module, SPI1.

If the receive buffer is full when new data is being

transferred from SPI1SR to SPI1BUF, the module will

set the SPIROV bit indicating an overflow condition.

The transfer of the data from SPI1SR to SPI1BUF is not

completed and the new data is lost. The module will not

respond to SCL transitions while SPIROV is ‘1’, effec-

tively disabling the module until SPI1BUF is read by

user software.

13.1 Operating Function Description

Transmit writes are also double-buffered. The user

writes to SPI1BUF. When the master or slave transfer

is completed, the contents of the shift register

(SPI1SR) are moved to the receive buffer. If any

transmit data has been written to the buffer register, the

contents of the transmit buffer are moved to SPI1SR.

The received data is thus placed in SPI1BUF and the

transmit data in SPI1SR is ready for the next transfer.

Figure 13-1 is a simplified block diagram of the SPI

module, which consists of a 16-bit shift register,

SPI1SR, used for shifting data in and out, and a buffer

register, SPI1BUF. Control register SPI1CON (not

shown) configures the module. Additionally, status

register SPI1STAT (not shown) indicates various status

conditions.

Note:

See “dsPIC30F Family Reference

Manual” (DS70046) for detailed

information on the control and status

registers.

Note:

Both the transmit buffer (SPI1TXB) and

the receive buffer (SPI1RXB) are mapped

to the same register address, SPI1BUF.

Four I/O pins comprise the serial interface:

• SDI1 (serial data input)

• SDO1 (serial data output)

• SCK1 (shift clock input or output)

• SS1 (active-low slave select).

Figure 13-2 depicts the a master/slave connection

between two processors. In Master mode, the clock is

generated by prescaling the system clock. Data is

transmitted as soon as a value is written to SPI1BUF.

The interrupt is generated at the middle of the transfer

of the last bit.

13.1.2

SDO1 DISABLE

A control bit, DISSDO, is provided to the SPI1CON

register to allow the SDO1 output to be disabled. This

will allow the SPI module to be connected in an input

only configuration. SDO1 can also be used for general

purpose I/O.

In Slave mode, data is transmitted and received as

external clock pulses appear on SCK. Again, the

interrupt is generated when the last bit is latched. If

SS1 control is enabled, then transmission and

reception are enabled only when SS1 = low. The SDO1

output will be disabled in SS1 mode with SS1 high.

13.2 Framed SPI Support

The module supports a basic framed SPI protocol in

Master or Slave mode. The control bit, FRMEN,

enables framed SPI support and causes the SS1 pin to

perform the Frame Synchronization Pulse (FSYNC)

function. The control bit, SPIFSD, determines whether

the SS1 pin is an input or an output (i.e., whether the

module receives or generates the Frame

Synchronization Pulse). The frame pulse is an

active-high pulse for a single SPI clock cycle. When

Frame Synchronization is enabled, the data

transmission starts only on the subsequent transmit

edge of the SPI clock.

The clock provided to the module is (FOSC/4). This

clock is then prescaled by the primary (PPRE<1:0>)

and the secondary (SPRE<2:0>) prescale factors. The

CKE bit determines whether transmit occurs on

transition from active clock state to Idle clock state, or

vice versa. The CKP bit selects the Idle state (high or

low) for the clock.

13.1.1

WORD AND BYTE

COMMUNICATION

A control bit, MODE16 (SPI1CON<10>), allows the

module to communicate in either 16-bit or 8-bit mode.

16-bit operation is identical to 8-bit operation except

that the number of bits transmitted is 16 instead of 8.

The user software must disable the module prior to

changing the MODE16 bit. The SPI module is reset

when the MODE16 bit is changed by the user.

A basic difference between 8-bit and 16-bit operation is

that the data is transmitted out of bit 7 of the SPI1SR

for 8-bit operation, and data is transmitted out of bit 15

of the SPI1SR for 16-bit operation. In both modes, data

is shifted into bit 0 of the SPI1SR.

13.3 Slave Select Synchronization

13.5 SPI Operation During CPU Idle

Mode

The SS1 pin allows a Synchronous Slave mode. The

SPI must be configured in SPI Slave mode with SS1

pin control enabled (SSEN = 1). When the SS1 pin is

low, transmission and reception are enabled and the

SDOx pin is driven. When SS1 pin goes high, the

SDOx pin is no longer driven. Also, the SPI module is

resynchronized, and all counters/control circuitry are

reset. Therefore, when the SS1 pin is asserted low

again, transmission/reception will begin at the MSb

even if SS1 had been de-asserted in the middle of a

transmit/receive.

When the device enters Idle mode, all clock sources

remain functional. The SPISIDL bit (SPI1STAT<13>)

selects if the SPI module will stop or continue on idle. If

SPISIDL = 0, the module will continue to operate when

the CPU enters Idle mode. If SPISIDL = 1, the module

will stop when the CPU enters Idle mode.

13.4 SPI Operation During CPU Sleep

Mode

During Sleep mode, the SPI module is shut down. If the

CPU enters Sleep mode while an SPI transaction is in

progress, then the transmission and reception is

aborted.

The transmitter and receiver will stop in Sleep mode.

However, register contents are not affected by entering

or exiting Sleep mode.

PIN CONFIGURATION IN I C MODE

I²C has a 2-pin interface; the SCL pin is clock and the

SDA pin is data.

The Inter-Integrated Circuit (I²C^TM) module provides

complete hardware support for both Slave and

Multi-Master modes of the I²C serial communication

standard, with a 16-bit interface.

14.1.3

I C REGISTERS

I2CCON and I2CSTAT are control and status registers,

respectively. The I2CCON register is readable and

writable. The lower 6 bits of I2CSTAT are read-only.

The remaining bits of the I2CSTAT are read/write.

This module offers the following key features:

• I²C interface supporting both master and slave

operation.

• I²C Slave mode supports 7-bit and 10-bit

addressing.

• I²C Master mode supports 7-bit and 10-bit

addressing.

• I²C port allows bidirectional transfers between

master and slaves.

• Serial clock synchronization for I²C port can be

used as a handshake mechanism to suspend and

resume serial transfer (SCLREL control).

I2CRSR is the shift register used for shifting data,

whereas I2CRCV is the buffer register to which data

bytes are written, or from which data bytes are read.

I2CRCV is the receive buffer as shown in Figure 14-1.

I2CTRN is the transmit register to which bytes are

written during a transmit operation, as shown in

Figure 14-2.

The I2CADD register holds the slave address. A Status

bit, ADD10, indicates 10-bit Address mode. The

I2CBRG acts as the Baud Rate Generator reload

value.

• I²C supports multi-master operation; detects bus

collision and will arbitrate accordingly.

In receive operations, I2CRSR and I2CRCV together

form

a double-buffered receiver. When I2CRSR

14.1 Operating Function Description

receives a complete byte, it is transferred to I2CRCV

and an interrupt pulse is generated. During

transmission, the I2CTRN is not double-buffered.

The hardware fully implements all the master and slave

functions of the I²C Standard and Fast mode

specifications, as well as 7 and 10-bit addressing.

Thus, the I²C module can operate either as a slave or

a master on an I²C bus.

Note:

Following a Restart condition in 10-bit

mode, the user only needs to match the

first 7-bit address.

14.2 I²C Module Addresses

14.3.2

SLAVE RECEPTION

If the R_W bit received is a ‘0’ during an address

match, then Receive mode is initiated. Incoming bits

are sampled on the rising edge of SCL. After 8 bits are

received, if I2CRCV is not full or I2COV is not set,

I2CRSR is transferred to I2CRCV. ACK is sent on the

ninth clock.

The I2CADD register contains the Slave mode

addresses. The register is a 10-bit register.

If the A10M bit (I2CCON<10>) is ‘0’, the address is

interpreted by the module as a 7-bit address. When an

address is received, it is compared to the 7 LSb of the

I2CADD register.

If the RBF flag is set, indicating that I2CRCV is still

holding data from a previous operation (RBF = 1), then

ACK is not sent; however, the interrupt pulse is

generated. In the case of an overflow, the contents of

the I2CRSR are not loaded into the I2CRCV.

If the A10M bit is ‘1’, the address is assumed to be a

10-bit address. When an address is received, it will be

compared with the binary value ‘11110 A9 A8’ (where

A9and A8are two Most Significant bits of I2CADD). If

that value matches, the next address will be compared

with the Least Significant 8 bits of I2CADD, as specified

in the 10-bit addressing protocol.

Note:

The I2CRCV will be loaded if the I2COV

bit = 1and the RBF flag = 0. In this case,

a read of the I2CRCV was performed but

the user did not clear the state of the

I2COV bit before the next receive

occurred. The acknowledgement is not

sent (ACK = 1) and the I2CRCV is

updated.

The 7-bit I²C Slave Addresses supported by the

dsPIC30F are shown in Table 14-1.

In 10-bit mode, the basic receive and transmit

0x7c-0x7f

Reserved

14.3 I²C 7-bit Slave Mode Operation

The A10M bit is a control bit that signifies that the

address in I2CADD is a 10-bit address rather than a 7-bit

address. The address detection protocol for the first byte

of a message address is identical for 7-bit and 10-bit

messages, but the bits being compared are different.

Once enabled (I2CEN = 1), the slave module will wait

for a Start bit to occur (i.e., the I²C module is ‘Idle’).

Following the detection of a Start bit, 8 bits are shifted

into I2CRSR and the address is compared against

I2CADD. In 7-bit mode (A10M = 0), bits I2CADD<6:0>

are compared against I2CRSR<7:1> and I2CRSR<0>

is the R_W bit. All incoming bits are sampled on the ris-

ing edge of SCL.

I2CADD holds the entire 10-bit address. Upon

receiving an address following a Start bit, I2CRSR

<7:3> is compared against a literal ‘11110’ (the default

10-bit address) and I2CRSR<2:1> are compared

against I2CADD<9:8>. If a match occurs and if

R_W = 0, the interrupt pulse is sent. The ADD10 bit will

be cleared to indicate a partial address match. If a

match fails or R_W = 1, the ADD10 bit is cleared and

the module returns to the Idle state.

If an address match occurs, an acknowledgement will

be sent, and the slave event interrupt flag (SI2CIF) is

set on the falling edge of the ninth (ACK) bit. The

address match does not affect the contents of the

I2CRCV buffer or the RBF bit.

The low byte of the address is then received and

compared with I2CADD<7:0>. If an address match

occurs, the interrupt pulse is generated and the ADD10

bit is set, indicating a complete 10-bit address match. If

an address match did not occur, the ADD10 bit is

cleared and the module returns to the Idle state.

14.3.1

SLAVE TRANSMISSION

If the R_W bit received is a ‘1’, then the serial port will

go into Transmit mode. It will send ACK on the ninth bit

and then hold SCL to ‘0’ until the CPU responds by

writing to I2CTRN. SCL is released by setting the

SCLREL bit, and 8 bits of data are shifted out. Data bits

are shifted out on the falling edge of SCL, such that

SDA is valid during SCL high. The interrupt pulse is

sent on the falling edge of the ninth clock pulse,

regardless of the status of the ACK received from the

master.

DS70139G-page 99

dsPIC30F2011/2012/3012/3013

Clock stretching takes place following the ninth clock of

the receive sequence. On the falling edge of the ninth

clock at the end of the ACK sequence, if the RBF bit is

set, the SCLREL bit is automatically cleared, forcing

the SCL output to be held low. The user’s ISR must set

the SCLREL bit before reception is allowed to continue.

By holding the SCL line low, the user has time to

service the ISR and read the contents of the I2CRCV

before the master device can initiate another receive

sequence. This will prevent buffer overruns from

occurring.

14.4.1

10-BIT MODE SLAVE

TRANSMISSION

Once a slave is addressed in this fashion with the full

10-bit address (we will refer to this state as

“PRIOR_ADDR_MATCH”), the master can begin

sending data bytes for a slave reception operation.

14.4.2

10-BIT MODE SLAVE RECEPTION

Once addressed, the master can generate a Repeated

Start, reset the high byte of the address and set the

R_W bit without generating a Stop bit, thus initiating a

slave transmit operation.

Note 1: If the user reads the contents of the

I2CRCV, clearing the RBF bit before the

falling edge of the ninth clock, the

SCLREL bit will not be cleared and clock

stretching will not occur.

14.5 Automatic Clock Stretch

In the Slave modes, the module can synchronize buffer

reads and write to the master device by clock stretching.

2: The SCLREL bit can be set in software

regardless of the state of the RBF bit. The

user should be careful to clear the RBF

bit in the ISR before the next receive

sequence in order to prevent an overflow

condition.

14.5.1

TRANSMIT CLOCK STRETCHING

Both 10-bit and 7-bit Transmit modes implement clock

stretching by asserting the SCLREL bit after the falling

edge of the ninth clock, if the TBF bit is cleared,

indicating the buffer is empty.

In Slave Transmit modes, clock stretching is always

performed irrespective of the STREN bit.

14.5.4

CLOCK STRETCHING DURING

10-BIT ADDRESSING (STREN = 1)

Clock synchronization takes place following the ninth

clock of the transmit sequence. If the device samples

an ACK on the falling edge of the ninth clock and if the

TBF bit is still clear, then the SCLREL bit is

automatically cleared. The SCLREL being cleared to

‘0’ will assert the SCL line low. The user’s ISR must set

the SCLREL bit before transmission is allowed to

continue. By holding the SCL line low, the user has time

to service the ISR and load the contents of the I2CTRN

before the master device can initiate another transmit

sequence.

Clock stretching takes place automatically during the

addressing sequence. Because this module has a

register for the entire address, it is not necessary for

the protocol to wait for the address to be updated.

After the address phase is complete, clock stretching

will occur on each data receive or transmit sequence as

was described earlier.

14.6 Software Controlled Clock

Stretching (STREN = 1)

Note 1: If the user loads the contents of I2CTRN,

setting the TBF bit before the falling edge

of the ninth clock, the SCLREL bit will not

be cleared and clock stretching will not

occur.

When the STREN bit is ‘1’, the SCLREL bit may be

cleared by software to allow software to control the

clock stretching. The logic will synchronize writes to the

SCLREL bit with the SCL clock. Clearing the SCLREL

bit will not assert the SCL output until the module

detects a falling edge on the SCL output and SCL is

sampled low. If the SCLREL bit is cleared by the user

while the SCL line has been sampled low, the SCL

output will be asserted (held low). The SCL output will

remain low until the SCLREL bit is set, and all other

devices on the I²C bus have de-asserted SCL. This

ensures that a write to the SCLREL bit will not violate

the minimum high time requirement for SCL.

2: The SCLREL bit can be set in software,

regardless of the state of the TBF bit.

14.5.2

RECEIVE CLOCK STRETCHING

The STREN bit in the I2CCON register can be used to

enable clock stretching in Slave Receive mode. When

the STREN bit is set, the SCL pin will be held low at the

end of each data receive sequence.

If the STREN bit is ‘0’, a software write to the SCLREL

bit will be disregarded and have no effect on the

SCLREL bit.

14.5.3

CLOCK STRETCHING DURING

7-BIT ADDRESSING (STREN = 1)

When the STREN bit is set in Slave Receive mode, the

SCL line is held low when the buffer register is full. The

method for stretching the SCL output is the same for

both 7 and 10-bit addressing modes.

DS70139G-page 100

dsPIC30F2011/2012/3012/3013

14.7 Interrupts

14.11 I²C Master Support

The I²C module generates two interrupt flags, MI2CIF

(I²C Master Interrupt Flag) and SI2CIF (I²C Slave

Interrupt Flag). The MI2CIF interrupt flag is activated

on completion of a master message event. The SI2CIF

interrupt flag is activated on detection of a message

directed to the slave.

As a master device, six operations are supported:

• Assert a Start condition on SDA and SCL.

• Assert a Restart condition on SDA and SCL.

• Write to the I2CTRN register initiating

transmission of data/address.

• Generate a Stop condition on SDA and SCL.

• Configure the I²C port to receive data.

14.8 Slope Control

• Generate an ACK condition at the end of a

received byte of data.

The I²C standard requires slope control on the SDA

and SCL signals for Fast mode (400 kHz). The control

bit, DISSLW, enables the user to disable slew rate

control if desired. It is necessary to disable the slew

rate control for 1 MHz mode.

14.12 I²C Master Operation

The master device generates all of the serial clock

pulses and the Start and Stop conditions. A transfer is

ended with a Stop condition or with a Repeated Start

condition. Since the Repeated Start condition is also

the beginning of the next serial transfer, the I²C bus will

not be released.

14.9 IPMI Support

The control bit, IPMIEN, enables the module to support

Intelligent Peripheral Management Interface (IPMI).

When this bit is set, the module accepts and acts upon

all addresses.

In Master Transmitter mode, serial data is output

through SDA, while SCL outputs the serial clock. The

first byte transmitted contains the slave address of the

receiving device (7 bits) and the data direction bit. In

this case, the data direction bit (R_W) is logic ‘0’. Serial

data is transmitted 8 bits at a time. After each byte is

transmitted, an ACK bit is received. Start and Stop

conditions are output to indicate the beginning and the

end of a serial transfer.

14.10 General Call Address Support

The general call address can address all devices.

When this address is used, all devices should, in

theory, respond with an acknowledgement.

The general call address is one of eight addresses

reserved for specific purposes by the I²C protocol. It

consists of all ‘0’s with R_W = 0.

In Master Receive mode, the first byte transmitted

contains the slave address of the transmitting device

(7 bits) and the data direction bit. In this case, the data

direction bit (R_W) is logic ‘1’. Thus, the first byte

transmitted is a 7-bit slave address, followed by a ‘1’ to

indicate receive bit. Serial data is received via SDA

while SCL outputs the serial clock. Serial data is

received 8 bits at a time. After each byte is received, an

ACK bit is transmitted. Start and Stop conditions

indicate the beginning and end of transmission.

The general call address is recognized when the

General Call Enable (GCEN) bit is set

(I2CCON<7> = 1). Following a Start bit detection, 8 bits

are shifted into I2CRSR and the address is compared

with I2CADD, and is also compared with the general

call address which is fixed in hardware.

If a general call address match occurs, the I2CRSR is

transferredtotheI2CRCVaftertheeighthclock,theRBF

flag is set and on the falling edge of the ninth bit (ACK

bit), the master event interrupt flag (MI2CIF) is set.

2

14.12.1 I C MASTER TRANSMISSION

When the interrupt is serviced, the source for the

interrupt can be checked by reading the contents of the

I2CRCV to determine if the address was device

specific or a general call address.

Transmission of a data byte, a 7-bit address, or the sec-

ond half of a 10-bit address, is accomplished by simply

writing a value to I2CTRN register. The user should

only write to I2CTRN when the module is in a WAIT

state. This action will set the Buffer Full Flag (TBF) and

allow the Baud Rate Generator to begin counting and

start the next transmission. Each bit of address/data

will be shifted out onto the SDA pin after the falling

edge of SCL is asserted. The Transmit Status Flag,

TRSTAT (I2CSTAT<14>), indicates that a master

transmit is in progress.

DS70139G-page 101

dsPIC30F2011/2012/3012/3013

2

If a transmit was in progress when the bus collision

14.12.2 I C MASTER RECEPTION

occurred, the transmission is halted, the TBF flag is

cleared, the SDA and SCL lines are de-asserted and a

value can now be written to I2CTRN. When the user

services the I²C master event Interrupt Service

Routine, if the I²C bus is free (i.e., the P bit is set), the

user can resume communication by asserting a Start

condition.

Master mode reception is enabled by programming the

Receive Enable bit, RCEN (I2CCON<3>). The I²C

module must be Idle before the RCEN bit is set,

otherwise the RCEN bit will be disregarded. The Baud

Rate Generator begins counting and on each rollover,

the state of the SCL pin ACK and data are shifted into

the I2CRSR on the rising edge of each clock.

If a Start, Restart, Stop or Acknowledge condition was

in progress when the bus collision occurred, the

condition is aborted, the SDA and SCL lines are

de-asserted, and the respective control bits in the

I2CCON register are cleared to ‘0’. When the user

services the bus collision Interrupt Service Routine,

and if the I²C bus is free, the user can resume

communication by asserting a Start condition.

14.12.3 BAUD RATE GENERATOR

In I²C Master mode, the reload value for the BRG is

located in the I2CBRG register. When the BRG is

loaded with this value, the BRG counts down to ‘0’ and

stops until another reload has taken place. If clock

arbitration is taking place, for instance, the BRG is

reloaded when the SCL pin is sampled high.

The master will continue to monitor the SDA and SCL

pins, and if a Stop condition occurs, the MI2CIF bit will

be set.

As per the I²C standard, FSCK may be 100 kHz or

400 kHz. However, the user can specify any baud rate

up to 1 MHz. I2CBRG values of ‘0’ or ‘1’ are illegal.

A write to the I2CTRN will start the transmission of data

at the first data bit regardless of where the transmitter

left off when bus collision occurred.

EQUATION 14-1: SERIAL CLOCK RATE

In a multi-master environment, the interrupt generation

on the detection of Start and Stop conditions allows the

determination of when the bus is free. Control of the I²C

bus can be taken when the P bit is set in the I2CSTAT

register, or the bus is Idle and the S and P bits are

cleared.

14.12.4 CLOCK ARBITRATION

Clock arbitration occurs when the master de-asserts

the SCL pin (SCL allowed to float high) during any

receive, transmit, or Restart/Stop condition. When the

SCL pin is allowed to float high, the Baud Rate

Generator (BRG) is suspended from counting until the

SCL pin is actually sampled high. When the SCL pin is

sampled high, the Baud Rate Generator is reloaded

with the contents of I2CBRG and begins counting. This

ensures that the SCL high time will always be at least

one BRG rollover count in the event that the clock is

held low by an external device.

14.13 I²C Module Operation During CPU

Sleep and Idle Modes

2

14.13.1 I C OPERATION DURING CPU

SLEEP MODE

When the device enters Sleep mode, all clock sources

to the module are shut down and stay at logic ‘0’. If

Sleep occurs in the middle of a transmission and the

state machine is partially into a transmission as the

clocks stop, then the transmission is aborted. Similarly,

if Sleep occurs in the middle of a reception, then the

reception is aborted.

14.12.5 MULTI-MASTER COMMUNICATION,

BUS COLLISION, AND BUS

ARBITRATION

2

14.13.2 I C OPERATION DURING CPU IDLE

Multi-master operation support is achieved by bus

arbitration. When the master outputs address/data bits

onto the SDA pin, arbitration takes place when the

master outputs a ‘1’ on SDA by letting SDA float high

while another master asserts a ‘0’. When the SCL pin

floats high, data should be stable. If the expected data

on SDA is a ‘1’ and the data sampled on the SDA

pin = 0, then a bus collision has taken place. The

master will set the MI2CIF pulse and reset the master

portion of the I²C port to its Idle state.

MODE

For the I²C, the I2CSIDL bit selects if the module will

stop on Idle or continue on Idle. If I2CSIDL = 0, the

module will continue operation on assertion of the Idle

mode. If I2CSIDL = 1, the module will stop on Idle.

15.2 Enabling and Setting Up UART

15.3 Transmitting Data

15.2.1

ENABLING THE UART

15.3.1

TRANSMITTING IN 8-BIT DATA

MODE

The UART module is enabled by setting the UARTEN

bit in the UxMODE register (where x = 1 or 2). Once

enabled, the UxTX and UxRX pins are configured as an

output and an input respectively, overriding the TRIS

and LAT register bit settings for the corresponding I/O

port pins. The UxTX pin is at logic ‘1’ when no

transmission is taking place.

The following steps must be performed to transmit 8-bit

data:

1. Set up the UART:

First, the data length, parity and number of Stop

bits must be selected. Then, the transmit and

receive interrupt enable and priority bits are

setup in the UxMODE and UxSTA registers.

Also, the appropriate baud rate value must be

written to the UxBRG register.

15.2.2

DISABLING THE UART

The UART module is disabled by clearing the UARTEN

bit in the UxMODE register. This is the default state

after any Reset. If the UART is disabled, all I/O pins

operate as port pins under the control of the LAT and

TRIS bits of the corresponding port pins.

2. Enable the UART by setting the UARTEN bit

(UxMODE<15>).

3. Set the UTXEN bit (UxSTA<10>), thereby

enabling a transmission.

Disabling the UART module resets the buffers to empty

states. Any data characters in the buffers are lost and

the baud rate counter is reset.

4. Write the byte to be transmitted to the lower byte

of UxTXREG. The value will be transferred to the

Transmit Shift register (UxTSR) immediately

and the serial bit stream will start shifting out

during the next rising edge of the baud clock.

Alternatively, the data byte may be written while

UTXEN = 0, following which, the user may set

UTXEN. This will cause the serial bit stream to

begin immediately because the baud clock will

start from a cleared state.

All error and status flags associated with the UART

module are reset when the module is disabled. The

URXDA, OERR, FERR, PERR, UTXEN, UTXBRK and

UTXBF bits are cleared, whereas RIDLE and TRMT

are set. Other control bits, including ADDEN,

URXISEL<1:0>, UTXISEL, as well as the UxMODE

and UxBRG registers, are not affected.

5.

A

transmit interrupt will be generated,

Clearing the UARTEN bit while the UART is active will

abort all pending transmissions and receptions and

reset the module as defined above. Re-enabling the

UART will restart the UART in the same configuration.

depending on the value of the interrupt control

bit UTXISEL (UxSTA<15>).

15.3.2

TRANSMITTING IN 9-BIT DATA

MODE

15.2.3

ALTERNATE I/O

The sequence of steps involved in the transmission

of 9-bit data is similar to 8-bit transmission, except that

a 16-bit data word (of which the upper 7 bits are always

clear) must be written to the UxTXREG register.

The alternate I/O function is enabled by setting the

ALTIO bit (UxMODE<10>). If ALTIO = 1, the UxATX

and UxARX pins (alternate transmit and alternate

receive pins, respectively) are used by the UART

module instead of the UxTX and UxRX pins. If

ALTIO = 0, the UxTX and UxRX pins are used by the

UART module.

15.3.3

TRANSMIT BUFFER (UXTXB)

The transmit buffer is 9 bits wide and 4 characters deep.

Including the Transmit Shift register (UxTSR), the user

effectively has a 5-deep FIFO (First-In, First- Out) buffer.

The UTXBF bit (UxSTA<9>) indicates whether the

transmit buffer is full.

15.2.4

SETTING UP DATA, PARITY AND

STOP BIT SELECTIONS

Control bits PDSEL<1:0> in the UxMODE register are

used to select the data length and parity used in the

transmission. The data length may either be 8 bits with

even, odd or no parity, or 9 bits with no parity.

If a user attempts to write to a full buffer, the new data

will not be accepted into the FIFO and no data shift will

occur within the buffer. This enables recovery from a

buffer overrun condition.

The STSEL bit determines whether one or two Stop bits

will be used during data transmission.

The FIFO is reset during any device Reset, but is not

affected when the device enters or wakes up from a

Power Saving mode.

The default (power-on) setting of the UART is 8 bits, no

parity and 1 Stop bit (typically represented as 8, N, 1).

DS70139G-page 107

dsPIC30F2011/2012/3012/3013

15.3.4

TRANSMIT INTERRUPT

15.4.2

RECEIVE BUFFER (UXRXB)

The transmit interrupt flag (U1TXIF or U2TXIF) is

located in the corresponding interrupt flag register.

The receive buffer is 4 words deep. Including the

Receive Shift register (UxRSR), the user effectively

has a 5-word deep FIFO buffer.

The transmitter generates an edge to set the UxTXIF

bit. The condition for generating the interrupt depends

on the UTXISEL control bit:

URXDA (UxSTA<0>) = 1 indicates that the receive

buffer has data available. URXDA = 0implies that the

buffer is empty. If a user attempts to read an empty

buffer, the old values in the buffer will be read and no

data shift will occur within the FIFO.

a) If UTXISEL = 0, an interrupt is generated when

a word is transferred from the transmit buffer to

the Transmit Shift register (UxTSR). This means

that the transmit buffer has at least one empty

word.

The FIFO is reset during any device Reset. It is not

affected when the device enters or wakes up from a

Power Saving mode.

b) If UTXISEL = 1, an interrupt is generated when

a word is transferred from the transmit buffer to

the Transmit Shift register (UxTSR) and the

transmit buffer is empty.

15.4.3

RECEIVE INTERRUPT

The receive interrupt flag (U1RXIF or U2RXIF) can be

read from the corresponding interrupt flag register. The

interrupt flag is set by an edge generated by the

receiver. The condition for setting the receive interrupt

flag depends on the settings specified by

the URXISEL<1:0> (UxSTA<7:6>) control bits.

Switching between the two Interrupt modes during

operation is possible and sometimes offers more

flexibility.

15.3.5

TRANSMIT BREAK

a) If URXISEL<1:0> = 00 or 01, an interrupt is

generated every time a data word is transferred

from the Receive Shift register (UxRSR) to the

receive buffer. There may be one or more

characters in the receive buffer.

Setting the UTXBRK bit (UxSTA<11>) will cause the

UxTX line to be driven to logic ‘0’. The UTXBRK bit

overrides all transmission activity. Therefore, the user

should generally wait for the transmitter to be Idle

before setting UTXBRK.

b) If URXISEL<1:0> = 10, an interrupt is generated

when a word is transferred from the Receive Shift

register (UxRSR) to the receive buffer, which as a

result of the transfer, contains 3 characters.

To send a Break character, the UTXBRK bit must be set

by software and must remain set for a minimum of 13

baud clock cycles. The UTXBRK bit is then cleared by

software to generate Stop bits. The user must wait for

a duration of at least one or two baud clock cycles in

order to ensure a valid Stop bit(s) before reloading the

UxTXB, or starting other transmitter activity.

Transmission of a Break character does not generate a

transmit interrupt.

c) If URXISEL<1:0> = 11, an interrupt is set when

a word is transferred from the Receive Shift

register (UxRSR) to the receive buffer, which as

a result of the transfer, contains 4 characters

(i.e., becomes full).

Switching between the Interrupt modes during

operation is possible, though generally not advisable

during normal operation.

15.4 Receiving Data

15.4.1

RECEIVING IN 8-BIT OR 9-BIT

DATA MODE

15.5 Reception Error Handling

The following steps must be performed while receiving

8-bit or 9-bit data:

15.5.1

RECEIVE BUFFER OVERRUN

ERROR (OERR BIT)

1. Set up the UART (see Section 15.3.1

“Transmitting in 8-bit data mode”).

The OERR bit (UxSTA<1>) is set if all of the following

conditions occur:

2. Enable the UART (see Section 15.3.1

“Transmitting in 8-bit data mode”).

a) The receive buffer is full.

3. A receive interrupt will be generated when one

ormoredatawordshavebeenreceived, depend-

ing on the receive interrupt settings specified by

the URXISEL bits (UxSTA<7:6>).

b) The Receive Shift register is full, but unable to

transfer the character to the receive buffer.

c) The Stop bit of the character in the UxRSR is

detected, indicating that the UxRSR needs to

transfer the character to the buffer.

4. ReadtheOERRbittodetermineifanoverrunerror

hasoccurred. TheOERRbitmustberesetinsoft-

ware.

Once OERR is set, no further data is shifted in UxRSR

(until the OERR bit is cleared in software or a Reset

occurs). The data held in UxRSR and UxRXREG

remains valid.

5. Read the received data from UxRXREG. The act

of reading UxRXREG will move the next word to

the top of the receive FIFO, and the PERR and

FERR values will be updated.

DS70139G-page 108

dsPIC30F2011/2012/3012/3013

15.5.2

FRAMING ERROR (FERR)

15.7 Loopback Mode

The FERR bit (UxSTA<2>) is set if a ‘0’ is detected

instead of a Stop bit. If two Stop bits are selected, both

Stop bits must be ‘1’, otherwise FERR will be set. The

read-only FERR bit is buffered along with the received

data. It is cleared on any Reset.

Setting the LPBACK bit enables this special mode in

which the UxTX pin is internally connected to the UxRX

pin. When configured for the Loopback mode, the

UxRX pin is disconnected from the internal UART

receive logic. However, the UxTX pin still functions as

in a normal operation.

15.5.3

PARITY ERROR (PERR)

To select this mode:

The PERR bit (UxSTA<3>) is set if the parity of the

received word is incorrect. This error bit is applicable

only if a Parity mode (odd or even) is selected. The

read-only PERR bit is buffered along with the received

data bytes. It is cleared on any Reset.

a) Configure UART for desired mode of operation.

b) Set LPBACK = 1to enable Loopback mode.

c) Enable transmission as defined in Section 15.3

“Transmitting Data”.

15.5.4

IDLE STATUS

15.8 Baud Rate Generator

When the receiver is active (i.e., between the initial

detection of the Start bit and the completion of the Stop

bit), the RIDLE bit (UxSTA<4>) is ‘0’. Between the com-

pletion of the Stop bit and detection of the next Start bit,

the RIDLE bit is ‘1’, indicating that the UART is Idle.

The UART has a 16-bit Baud Rate Generator to allow

maximum flexibility in baud rate generation. The Baud

Rate Generator register (UxBRG) is readable and

writable. The baud rate is computed as follows:

BRG = 16-bit value held in UxBRG register

(0 through 65535)

15.5.5

RECEIVE BREAK

The receiver will count and expect a certain number of

bittimesbasedonthevaluesprogrammedinthePDSEL

(UxMODE<2:1>) and STSEL (UxMODE<0>) bits.

FCY = Instruction Clock Rate (1/TCY)

The baud rate is given by Equation 15-1.

If the break is longer than 13 bit times, the reception is

considered complete after the number of bit times

specified by PDSEL and STSEL. The URXDA bit is set,

FERR is set, zeros are loaded into the receive FIFO,

interrupts are generated if appropriate and the RIDLE

bit is set.

EQUATION 15-1: BAUD RATE

Baud Rate = FCY / (16*(BRG+1))

Therefore, the maximum baud rate possible is:

FCY /16 (if BRG = 0),

When the module receives a long break signal and the

receiver has detected the Start bit, the data bits and the

invalid Stop bit (which sets the FERR), the receiver

must wait for a valid Stop bit before looking for the next

Start bit. It cannot assume that the break condition on

the line is the next Start bit.

and the minimum baud rate possible is:

FCY / (16* 65536).

With a full 16-bit Baud Rate Generator at 30 MIPS

operation, the minimum baud rate achievable is

28.5 bps.

Break is regarded as a character containing all ‘0’s with

the FERR bit set. The Break character is loaded into

the buffer. No further reception can occur until a Stop bit

is received. Note that RIDLE goes high when the Stop

bit has not yet been received.

15.9 Auto-Baud Support

To allow the system to determine baud rates of

received characters, the input can be optionally linked

to a selected capture input (IC1 for UART1 and IC2 for

UART2). To enable this mode, you must program the

input capture module to detect the falling and rising

edges of the Start bit.

15.6 Address Detect Mode

Setting the ADDEN bit (UxSTA<5>) enables this

special mode in which a 9th bit (URX8) value of ‘1’

identifies the received word as an address, rather than

data. This mode is only applicable for 9-bit data

communication. The URXISEL control bit does not

have any impact on interrupt generation in this mode

since an interrupt (if enabled) will be generated every

time the received word has the 9th bit set.

DS70139G-page 109

dsPIC30F2011/2012/3012/3013

15.10 UART Operation During CPU

Sleep and Idle Modes

15.10.1 UART OPERATION DURING CPU

SLEEP MODE

When the device enters Sleep mode, all clock sources

to the module are shut down and stay at logic ‘0’. If

entry into Sleep mode occurs while a transmission is in

progress, then the transmission is aborted. The UxTX

pin is driven to logic ‘1’. Similarly, if entry into Sleep

mode occurs while a reception is in progress, then the

reception is aborted. The UxSTA, UxMODE, transmit

and receive registers and buffers, and the UxBRG

register are not affected by Sleep mode.

If the WAKE bit (UxMODE<7>) is set before the device

enters Sleep mode, then a falling edge on the UxRX pin

will generate a receive interrupt. The Receive Interrupt

Select mode bit (URXISEL) has no effect for this

function. If the receive interrupt is enabled, then this will

wake-up the device from Sleep. The UARTEN bit must

be set in order to generate a wake-up interrupt.

15.10.2 UART OPERATION DURING CPU

IDLE MODE

For the UART, the USIDL bit selects if the module will

stop operation when the device enters Idle mode or

whether the module will continue on Idle. If USIDL = 0,

the module will continue to operate during Idle mode. If

USIDL = 1, the module will stop on Idle.

NOTES:

DS70139G-page 112

dsPIC30F2011/2012/3012/3013

The ADC module has six 16-bit registers:

16.0 12-BIT ANALOG-TO-DIGITAL

• A/D Control Register 1 (ADCON1)

• A/D Control Register 2 (ADCON2)

• A/D Control Register 3 (ADCON3)

• A/D Input Select Register (ADCHS)

• A/D Port Configuration Register (ADPCFG)

• A/D Input Scan Selection Register (ADCSSL)

CONVERTER (ADC) MODULE

Note:

This data sheet summarizes features of

this group of dsPIC30F devices and is not

intended to be a complete reference

source. For more information on the CPU,

peripherals, register descriptions and

general device functionality, refer to the

“dsPIC30F Family Reference Manual”

(DS70046).

The ADCON1, ADCON2 and ADCON3 registers

control the operation of the ADC module. The ADCHS

register selects the input channels to be converted. The

ADPCFG register configures the port pins as analog

inputs or as digital I/O. The ADCSSL register selects

inputs for scanning.

The 12-bit Analog-to-Digital Converter allows

conversion of an analog input signal to a 12-bit digital

number. This module is based on a Successive

Approximation Register (SAR) architecture and

provides a maximum sampling rate of 200 ksps. The

ADC module has up to 10 analog inputs which are

multiplexed into a sample and hold amplifier. The

output of the sample and hold is the input into the

converter which generates the result. The analog

reference voltage is software selectable to either the

device supply voltage (AVDD/AVSS) or the voltage level

on the (VREF+/VREF-) pin. The ADC has a unique

feature of being able to operate while the device is in

Sleep mode with RC oscillator selection.

Note:

The SSRC<2:0>, ASAM, SMPI<3:0>,

BUFM and ALTS bits, as well as the

ADCON3 and ADCSSL registers, must

not be written to while ADON = 1. This

would lead to indeterminate results.

The block diagram of the 12-bit ADC module is shown

in Figure 16-1.

16.1 A/D Result Buffer

16.3 Selecting the Conversion

Sequence

The module contains a 16-word dual port read-only

buffer, called ADCBUF0...ADCBUFF, to buffer the A/D

results. The RAM is 12 bits wide but the data obtained

is represented in one of four different 16-bit data

formats. The contents of the sixteen A/D Conversion

Result Buffer registers, ADCBUF0 through ADCBUFF,

cannot be written by user software.

Several groups of control bits select the sequence in

which the A/D connects inputs to the sample/hold

channel, converts a channel, writes the buffer memory

and generates interrupts.

The sequence is controlled by the sampling clocks.

The

SMPI

bits

select

the

number

of

acquisition/conversion sequences that would be per-

formed before an interrupt occurs. This can vary from 1

sample per interrupt to 16 samples per interrupt.

16.2 Conversion Operation

After the ADC module has been configured, the sample

acquisition is started by setting the SAMP bit. Various

sources, such as a programmable bit, timer time-outs

and external events, will terminate acquisition and start

a conversion. When the A/D conversion is complete,

the result is loaded into ADCBUF0...ADCBUFF, and

the DONE bit and the A/D interrupt flag, ADIF, are set

after the number of samples specified by the SMPI bit.

The ADC module can be configured for different inter-

rupt rates as described in Section 16.3 “Selecting the

Conversion Sequence”.

The BUFM bit will split the 16-word results buffer into

two 8-word groups. Writing to the 8-word buffers will be

alternated on each interrupt event.

Use of the BUFM bit will depend on how much time is

available for the moving of the buffers after the

interrupt.

If the processor can quickly unload a full buffer within

the time it takes to acquire and convert one channel,

the BUFM bit can be ‘0’ and up to 16 conversions

(corresponding to the 16 input channels) may be done

per interrupt. The processor will have one acquisition

and conversion time to move the sixteen conversions.

The following steps should be followed for doing an

A/D conversion:

1. Configure the ADC module:

If the processor cannot unload the buffer within the

acquisition and conversion time, the BUFM bit should be

‘1’. For example, if SMPI<3:0> (ADCON2<5:2>) = 0111,

then eight conversions will be loaded into 1/2 of the

buffer, following which an interrupt occurs. The next

eight conversions will be loaded into the other 1/2 of the

buffer. The processor will have the entire time between

interrupts to move the eight conversions.

• Configure analog pins, voltage reference and

digital I/O

• Select A/D input channels

• Select A/D conversion clock

• Select A/D conversion trigger

• Turn on ADC module

2. Configure A/D interrupt (if required):

• Clear ADIF bit

The ALTS bit can be used to alternate the inputs

selected during the sampling sequence. The input

multiplexer has two sets of sample inputs: MUX A and

MUX B. If the ALTS bit is ‘0’, only the MUX A inputs are

selected for sampling. If the ALTS bit is ‘1’ and

SMPI<3:0> = 0000 on the first sample/convert

sequence, the MUX A inputs are selected and on the

next acquire/convert sequence, the MUX B inputs are

selected.

• Select A/D interrupt priority

3. Start sampling

4. Wait the required acquisition time

5. Trigger acquisition end, start conversion

6. Wait for A/D conversion to complete, by either:

• Waiting for the A/D interrupt, or

• Waiting for the DONE bit to get set

7. Read A/D result buffer; clear ADIF if required

The CSCNA bit (ADCON2<10>) will allow the

multiplexer input to be alternately scanned across a

selected number of analog inputs for the MUX A group.

The inputs are selected by the ADCSSL register. If a

particular bit in the ADCSSL register is ‘1’, the

corresponding input is selected. The inputs are always

scanned from lower to higher numbered inputs, starting

after each interrupt. If the number of inputs selected is

greater than the number of samples taken per interrupt,

the higher numbered inputs are unused.

DS70139G-page 114

dsPIC30F2011/2012/3012/3013

The internal RC oscillator is selected by setting the

ADRC bit.

16.4 Programming the Start of

Conversion Trigger

For correct ADC conversions, the ADC conversion

clock (TAD) must be selected to ensure a minimum TAD

time of 334 nsec (for VDD = 5V). Refer to Section 20.0

“Electrical Characteristics” for minimum TAD under

other operating conditions.

The conversion trigger will terminate acquisition and

start the requested conversions.

The SSRC<2:0> bits select the source of the

conversion trigger. The SSRC bits provide for up to four

alternate sources of conversion trigger.

Example 16-1 shows a sample calculation for the

ADCS<5:0> bits, assuming a device operating speed

of 30 MIPS.

When SSRC<2:0> = 000, the conversion trigger is

under software control. Clearing the SAMP bit will

cause the conversion trigger.

EXAMPLE 16-1:

ADC CONVERSION

CLOCK AND SAMPLING

RATE CALCULATION

When SSRC<2:0> = 111 (Auto-Start mode), the

conversion trigger is under A/D clock control. The

SAMC bits select the number of A/D clocks between

the start of acquisition and the start of conversion. This

provides the fastest conversion rates on multiple

channels. SAMC must always be at least one clock

cycle.

Minimum TAD = 334 nsec

TCY = 33 .33 nsec (30 MIPS)

16.5 Aborting a Conversion

Therefore,

Clearing the ADON bit during a conversion will abort

the current conversion and stop the sampling

sequencing until the next sampling trigger. The

ADCBUF will not be updated with the partially

completed A/D conversion sample. That is, the

ADCBUF will continue to contain the value of the last

completed conversion (or the last value written to the

ADCBUF register).

(19 + 1)

= 334 nsec

If SSRC<2:0> = ‘111’ and SAMC<4:0> = ‘00001’

If the clearing of the ADON bit coincides with an

auto-start, the clearing has a higher priority and a new

conversion will not start.

Since,

Sampling Time = Acquisition Time + Conversion Time

= 1 TAD + 14 TAD

After the A/D conversion is aborted, a 2 TAD wait is

required before the next sampling may be started by

setting the SAMP bit.

Therefore,

vide the required setup values for the conversion

speeds above 100 ksps.

The following figure shows the timing diagram of the

ADC running at 200 ksps. The TAD selection in

conjunction with the guidelines described above allows

a conversion speed of 200 ksps. See Example 16-1 for

code example.

16.7.1

200 KSPS CONFIGURATION

GUIDELINE

16.8 A/D Acquisition Requirements

The following configuration items are required to

achieve a 200 ksps conversion rate.

The analog input model of the 12-bit ADC is shown in

Figure 16-3. The total sampling time for the A/D is a

function of the internal amplifier settling time and the

holding capacitor charge time.

• Comply with conditions provided in Table 16-1.

• Connect external VREF+ and VREF- pins following

the recommended circuit shown in Figure 16-2.

• Set SSRC<2.0> = 111in the ADCON1 register to

enable the auto convert option.

For the ADC to meet its specified accuracy, the charge

holding capacitor (CHOLD) must be allowed to fully

charge to the voltage level on the analog input pin. The

• Enable automatic sampling by setting the ASAM

control bit in the ADCON1 register.

source

impedance

(RS),

the

interconnect

impedance (RIC) and the internal sampling switch

(RSS) impedance combine to directly affect the time

required to charge the capacitor CHOLD. The combined

impedance of the analog sources must therefore be

small enough to fully charge the holding capacitor

within the chosen sample time. To minimize the effects

of pin leakage currents on the accuracy of the ADC, the

maximum recommended source impedance, RS,

is 2.5 kΩ. After the analog input channel is selected

(changed), this sampling function must be completed

prior to starting the conversion. The internal holding

capacitor will be in a discharged state prior to each

sample operation.

• Write the SMPI<3.0> control bits in the ADCON2

register for the desired number of conversions

between interrupts.

• Configure the ADC clock period to be:

1

= 334 ns

(14 + 1) x 200,000

by writing to the ADCS<5:0> control bits in the

ADCON3 register.

• Configure the sampling time to be 1 TAD by

writing: SAMC<4:0> = 00001.

If the A/D interrupt is enabled, the device will wake-up

16.9 Module Power-Down Modes

from Sleep. If the A/D interrupt is not enabled, the ADC

module will then be turned off, although the ADON bit

will remain set.

The module has two internal power modes.

When the ADON bit is ‘1’, the module is in Active mode;

it is fully powered and functional.

16.10.2 A/D OPERATION DURING CPU IDLE

MODE

When ADON is ‘0’, the module is in Off mode. The

digital and analog portions of the circuit are disabled for

maximum current savings.

The ADSIDL bit selects if the module will stop on Idle or

continue on Idle. If ADSIDL = 0, the module will

continue operation on assertion of Idle mode. If

ADSIDL = 1, the module will stop on Idle.

In order to return to the Active mode from Off mode, the

user must wait for the ADC circuitry to stabilize.

16.10 A/D Operation During CPU Sleep

and Idle Modes

16.11 Effects of a Reset

A device Reset forces all registers to their Reset state.

This forces the ADC module to be turned off, and any

conversion and sampling sequence is aborted. The

values that are in the ADCBUF registers are not

modified. The A/D Result register will contain unknown

data after a Power-on Reset.

16.10.1 A/D OPERATION DURING CPU

SLEEP MODE

When the device enters Sleep mode, all clock sources

to the module are shut down and stay at logic ‘0’.

If Sleep occurs in the middle of a conversion, the

conversion is aborted. The converter will not continue

with a partially completed conversion on exit from

Sleep mode.

16.12 Output Formats

The A/D result is 12 bits wide. The data buffer RAM is

also 12 bits wide. The 12-bit data can be read in one of

four different formats. The FORM<1:0> bits select the

format. Each of the output formats translates to a 16-bit

result on the data bus.

Register contents are not affected by the device

entering or leaving Sleep mode.

The ADC module can operate during Sleep mode if the

A/D clock source is set to RC (ADRC = 1). When the

RC clock source is selected, the ADC module waits

one instruction cycle before starting the conversion.

This allows the SLEEPinstruction to be executed which

eliminates all digital switching noise from the

conversion. When the conversion is complete, the

CONV bit will be cleared and the result loaded into the

ADCBUF register.

16.14 Connection Considerations

The use of the ADPCFG and TRIS registers control the

operation of the A/D port pins. The port pins that are

desired as analog inputs must have their

corresponding TRIS bit set (input). If the TRIS bit is

cleared (output), the digital output level (VOH or VOL)

will be converted.

The analog inputs have diodes to VDD and VSS as ESD

protection. This requires that the analog input be

between VDD and VSS. If the input voltage exceeds this

range by greater than 0.3V (either direction), one of the

diodes becomes forward biased and it may damage the

device if the input current specification is exceeded.

The A/D operation is independent of the state of the

CH0SA<3:0>/CH0SB<3:0> bits and the TRIS bits.

An external RC filter is sometimes added for

anti-aliasing of the input signal. The R component

should be selected to ensure that the sampling time

requirements are satisfied. Any external components

connected (via high-impedance) to an analog input pin

(capacitor, zener diode, etc.) should have very little

leakage current at the pin.

When reading the PORT register, all pins configured as

analog input channels will read as cleared.

Pins configured as digital inputs will not convert an

analog input. Analog levels on any pin that is defined as

a digital input (including the ANx pins) may cause the

input buffer to consume current that exceeds the

device specifications.

17.1 Oscillator System Overview

17.0 SYSTEM INTEGRATION

The dsPIC30F oscillator system has the following

modules and features:

Note:

This data sheet summarizes features of

this group of dsPIC30F devices and is not

intended to be a complete reference

source. For more information on the CPU,

peripherals, register descriptions and

general device functionality, refer to the

“dsPIC30F Family Reference Manual”

(DS70046). For more information on the

device instruction set and programming,

refer to the “16-bit MCU and DSC

• Various external and internal oscillator options as

clock sources

• An on-chip PLL to boost internal operating

frequency

• A clock switching mechanism between various

clock sources

• Programmable clock postscaler for system power

savings

Programmer’s

Reference

Manual”

• A Fail-Safe Clock Monitor (FSCM) that detects

clock failure and takes fail-safe measures

(DS70157).

There are several features intended to maximize

system reliability, minimize cost through elimination of

external components, provide Power Saving Operating

modes and offer code protection:

• Clock Control register (OSCCON)

• Configuration bits for main oscillator selection

Configuration bits determine the clock source upon

Power-on Reset (POR) and Brown-out Reset (BOR).

Thereafter, the clock source can be changed between

permissible clock sources. The OSCCON register

controls the clock switching and reflects system clock

related status bits.

• Oscillator Selection

• Reset

- Power-on Reset (POR)

- Power-up Timer (PWRT)

- Oscillator Start-up Timer (OST)

- Programmable Brown-out Reset (BOR)

• Watchdog Timer (WDT)

• Low-Voltage Detect

Table 17-1 provides a summary of the dsPIC30F

Oscillator Operating modes. A simplified diagram of the

oscillator system is shown in Figure 17-1.

• Power-Saving Modes (Sleep and Idle)

• Code Protection

• Unit ID Locations

• In-Circuit Serial Programming (ICSP)

dsPIC30F devices have a Watchdog Timer which is

permanently enabled via the Configuration bits or can

be software controlled. It runs off its own RC oscillator

for added reliability. There are two timers that offer

necessary delays on power-up. One is the Oscillator

Start-up Timer (OST), intended to keep the chip in

Reset until the crystal oscillator is stable. The other is

the Power-up Timer (PWRT) which provides a delay on

power-up only, designed to keep the part in Reset while

the power supply stabilizes. With these two timers

on-chip, most applications need no external Reset

circuitry.

Sleep mode is designed to offer a very low current

Power-Down mode. The user can wake-up from Sleep

through external Reset, Watchdog Timer Wake-up, or

through an interrupt. Several oscillator options are also

made available to allow the part to fit a wide variety of

applications. In the Idle mode, the clock sources are

still active but the CPU is shut-off. The RC oscillator

option saves system cost while the LP crystal option

saves power.

(OST)

17.2 Oscillator Configurations

17.2.1

INITIAL CLOCK SOURCE

SELECTION

In order to ensure that a crystal oscillator (or ceramic

resonator) has started and stabilized, an Oscillator

Start-up Timer is included. It is a simple 10-bit counter

that counts 1024 TOSC cycles before releasing the

oscillator clock to the rest of the system. The time-out

period is designated as TOST.

While coming out of Power-on Reset or Brown-out

Reset, the device selects its clock source based on:

a) FOS<2:0> Configuration bits that select one of

four oscillator groups,

The TOST time is involved every time the oscillator has

to restart (i.e., on POR, BOR and wake-up from Sleep).

The Oscillator Start-up Timer is applied to the LP

oscillator, XT, XTL and HS modes (upon wake-up from

Sleep, POR and BOR) for the primary oscillator.

b) and FPR<4:0> Configuration bits that select one

of 15 oscillator choices within the primary group.

The selection is as shown in Table 17-2.

selected at all times.

If OSCCON<14:12> are set to ‘111’ and FPR<4:0> are

set to ‘00001’, ‘01010’ or ‘00011’, a PLL multiplier of

4, 8 or 16 (respectively) is applied.

17.2.3

LP OSCILLATOR CONTROL

Enabling the LP oscillator is controlled with two elements:

• The current oscillator group bits COSC<2:0>.

• The LPOSCEN bit (OSCCON register).

Note:

When a 16x PLL is used, the FRC fre-

quency must not be tuned to a frequency

greater than 7.5 MHz.

The LP oscillator is on (even during Sleep mode) if

LPOSCEN = 1. The LP oscillator is the device clock if:

• COSC<2:0> = 000(LP selected as main osc.) and

• LPOSCEN = 1

and output frequency ranges are summarized in

The PLL features a lock output which is asserted when

the PLL enters a phase locked state. Should the loop

fall out of lock (e.g., due to noise), the lock signal will be

rescinded. The state of this signal is reflected in the

read-only LOCK bit in the OSCCON register.

17.2.6

LOW-POWER RC OSCILLATOR (LPRC)

The LPRC oscillator is a component of the Watchdog

Timer (WDT) and oscillates at a nominal frequency of

512 kHz. The LPRC oscillator is the clock source for

the Power-up Timer (PWRT) circuit, WDT and clock

monitor circuits. It may also be used to provide a

low-frequency clock source option for applications

where power consumption is critical and timing

accuracy is not required.

17.2.5

FAST RC OSCILLATOR (FRC)

The FRC oscillator is a fast (7.37 MHz ±2% nominal)

internal RC oscillator. This oscillator is intended to

provide reasonable device operating speeds without

the use of an external crystal, ceramic resonator, or RC

network. The FRC oscillator can be used with the PLL

to obtain higher clock frequencies.

The LPRC oscillator is always enabled at a Power-on

Reset because it is the clock source for the PWRT.

After the PWRT expires, the LPRC oscillator will remain

on if one of the following is true:

The dsPIC30F operates from the FRC oscillator when-

ever the current oscillator selection control bits in the

OSCCON register (OSCCON<14:12>) are set to ‘001’.

• The Fail-Safe Clock Monitor is enabled

• The WDT is enabled

• The LPRC oscillator is selected as the system

clock via the COSC<2:0> control bits in the

OSCCON register

The four bit field specified by TUN<3:0> (OSCTUN

<3:0>) allows the user to tune the internal fast RC

oscillator (nominal 7.37 MHz). The user can tune the

FRC oscillator within a range of +10.5% (840 kHz)

and -12% (960 kHz) in steps of 1.50% around the

factory calibrated setting, as shown in Table 17-4.

If one of the above conditions is not true, the LPRC will

shut-off after the PWRT expires.

Note 1: OSC2 pin function is determined by the

Primary Oscillator mode selection

(FPR<4:0>).

Note:

OSCTUN functionality has been provided

to help customers compensate for

temperature effects on the FRC frequency

over a wide range of temperatures. The

tuning step size is an approximation and is

neither characterized nor tested.

2: OSC1 pin cannot be used as an I/O pin

even if the secondary oscillator or an

internal clock source is selected at all

times.

DS70139G-page 127

dsPIC30F2011/2012/3012/3013

The OSCCON register holds the Control and Status

bits related to clock switching.

17.2.7

FAIL-SAFE CLOCK MONITOR

The Fail-Safe Clock Monitor (FSCM) allows the device

to continue to operate even in the event of an oscillator

failure. The FSCM function is enabled by appropriately

programming the FCKSM Configuration bits (clock

switch and monitor selection bits) in the FOSC Device

Configuration register. If the FSCM function is enabled,

the LPRC internal oscillator will run at all times (except

during Sleep mode) and will not be subject to control by

the SWDTEN bit.

• COSC<2:0>: Read-only bits always reflect the

current oscillator group in effect.

• NOSC<2:0>: Control bits which are written to

indicate the new oscillator group of choice.

- On POR and BOR, COSC<2:0> and

NOSC<2:0> are both loaded with the

Configuration bit values FOS<2:0>.

• LOCK: The LOCK bit indicates a PLL lock.

In the event of an oscillator failure, the FSCM will gen-

erate a clock failure trap event and will switch the sys-

tem clock over to the FRC oscillator. The user will then

have the option to either attempt to restart the oscillator

or execute a controlled shutdown. The user may decide

to treat the trap as a warm Reset by simply loading the

Reset address into the oscillator fail trap vector. In this

event, the CF (Clock Fail) bit (OSCCON<3>) is also set

whenever a clock failure is recognized.

• CF: Read-only bit indicating if a clock fail detect

has occurred.

• OSWEN: Control bit changes from a ‘0’ to a ‘1’

when a clock transition sequence is initiated.

Clearing the OSWEN control bit will abort a clock

transition in progress (used for hang-up

situations).

If Configuration bits FCKSM<1:0> = 1x, then the clock

switching and Fail-Safe Clock monitoring functions are

disabled. This is the default Configuration bit setting.

In the event of a clock failure, the WDT is unaffected

and continues to run on the LPRC clock.

If clock switching is disabled, then the FOS<2:0> and

FPR<4:0> bits directly control the oscillator selection

and the COSC<2:0> bits do not control the clock selec-

tion. However, these bits will reflect the clock source

selection.

If the oscillator has a very slow start-up time coming out

of POR, BOR or Sleep, it is possible that the PWRT

timer will expire before the oscillator has started. In

such cases, the FSCM will be activated and the FSCM

will initiate a clock failure trap, and the COSC<2:0> bits

are loaded with FRC oscillator selection. This will

effectively shut-off the original oscillator that was trying

to start.

Note:

The application should not attempt to

switch to a clock of frequency lower than

100 kHz when the Fail-Safe Clock Monitor

is enabled. If such clock switching is

performed, the device may generate an

oscillator fail trap and switch to the Fast

RC oscillator.

The user may detect this situation and restart the

oscillator in the clock fail trap ISR.

Upon a clock failure detection, the FSCM module will

initiate a clock switch to the FRC oscillator as follows:

1. The COSC bits (OSCCON<14:12>) are loaded

with the FRC oscillator selection value.

17.2.8

PROTECTION AGAINST

ACCIDENTAL WRITES TO OSCCON

2. CF bit is set (OSCCON<3>).

A write to the OSCCON register is intentionally made

difficult because it controls clock switching and clock

scaling.

3. OSWEN control bit (OSCCON<0>) is cleared.

For the purpose of clock switching, the clock sources

are sectioned into four groups:

To write to the OSCCON low byte, the following code

sequence must be executed without any other

instructions in between:

• Primary (with or without PLL)

• Secondary

Byte Write 0x46 to OSCCON low

Byte Write 0x57 to OSCCON low

• Internal FRC

• Internal LPRC

Byte write is allowed for one instruction cycle. Write the

desired value or use bit manipulation instruction.

The user can switch between these functional groups

but cannot switch between options within a group. If the

primary group is selected, then the choice within the

group is always determined by the FPR<4:0>

Configuration bits.

To write to the OSCCON high byte, the following

instructions must be executed without any other

instructions in between:

Byte Write0x78to OSCCON high

Byte Write0x9Ato OSCCON high

Byte write is allowed for one instruction cycle. Write the

desired value or use bit manipulation instruction.

DS70139G-page 128

dsPIC30F2011/2012/3012/3013

17.3.1

POR: POWER-ON RESET

17.3 Reset

A power-on event will generate an internal POR pulse

when a VDD rise is detected. The Reset pulse will occur

at the POR circuit threshold voltage (VPOR) which is

nominally 1.85V. The device supply voltage

characteristics must meet specified starting voltage

and rise rate requirements. The POR pulse will reset a

POR timer and place the device in the Reset state. The

POR also selects the device clock source identified by

the oscillator configuration fuses.

The

dsPIC30F2011/2012/3012/3013

devices

differentiate between various kinds of Reset:

a) Power-on Reset (POR)

b) MCLR Reset during normal operation

c) MCLR Reset during Sleep

d) Watchdog Timer (WDT) Reset (during normal

operation)

e) Programmable Brown-out Reset (BOR)

f) RESETInstruction

The POR circuit inserts a small delay, TPOR, which is

nominally 10 μs and ensures that the device bias

circuits are stable. Furthermore, a user selected

power-up time-out (TPWRT) is applied. The TPWRT

parameter is based on device Configuration bits and

can be 0 ms (no delay), 4 ms, 16 ms or 64 ms. The total

delay is at device power-up, TPOR + TPWRT. When

these delays have expired, SYSRST will be negated on

the next leading edge of the Q1 clock and the PC will

jump to the Reset vector.

g) Reset caused by trap lockup (TRAPR)

h) Reset caused by illegal opcode or by using an

uninitialized W register as an address pointer

(IOPUWR)

Different registers are affected in different ways by

various Reset conditions. Most registers are not

affected by a WDT wake-up since this is viewed as the

resumption of normal operation. Status bits from the

RCON register are set or cleared differently in different

Reset situations, as indicated in Table 17-5. These bits

are used in software to determine the nature of the

Reset.

The timing for the SYSRST signal is shown in

Figure 17-3 through Figure 17-5.

A block diagram of the On-Chip Reset Circuit is shown

in Figure 17-2.

A MCLR noise filter is provided in the MCLR Reset

path. The filter detects and ignores small pulses.

Internally generated Resets do not drive MCLR pin low.

A BOR will generate a Reset pulse which will reset the

device. The BOR will select the clock source based on

the device Configuration bit values (FOS<2:0> and

FPR<4:0>). Furthermore, if an Oscillator mode is

selected, the BOR will activate the Oscillator Start-up

Timer (OST). The system clock is held until OST

expires. If the PLL is used, then the clock will be held

until the LOCK bit (OSCCON<5>) is ‘1’.

17.3.1.1

POR with Long Crystal Start-up Time

(with FSCM Enabled)

The oscillator start-up circuitry is not linked to the POR

circuitry. Some crystal circuits (especially low

frequency crystals) will have a relatively long start-up

time. Therefore, one or more of the following conditions

is possible after the POR timer and the PWRT have

expired:

Concurrently, the POR time-out (TPOR) and the PWRT

time-out (TPWRT) will be applied before the internal Reset

is released. If TPWRT = 0and a crystal oscillator is being

used, then a nominal delay of TFSCM = 100 μs is applied.

The total delay in this case is (TPOR + TFSCM).

• The oscillator circuit has not begun to oscillate.

• The Oscillator Start-up Timer has not expired (if a

crystal oscillator is used).

• The PLL has not achieved a LOCK (if PLL is

used).

The BOR Status bit (RCON<1>) will be set to indicate

that a BOR has occurred. The BOR circuit, if enabled,

will continue to operate while in Sleep or Idle modes

and will reset the device should VDD fall below the BOR

threshold voltage.

If the FSCM is enabled and one of the above conditions

is true, then a clock failure trap will occur. The device

will automatically switch to the FRC oscillator and the

user can switch to the desired crystal oscillator in the

trap ISR.

If the FSCM is disabled and the Power-up Timer

FRC, LPRC, ERC or EC, it will be active immediately.

If the FSCM is disabled and the system clock has not

17.3.2

BOR: PROGRAMMABLE

BROWN-OUT RESET

The BOR (Brown-out Reset) module is based on an

internal voltage reference circuit. The main purpose of

the BOR module is to generate a device Reset when a

brown-out condition occurs. Brown-out conditions are

generally caused by glitches on the AC mains

(i.e., missing portions of the AC cycle waveform due to

bad power transmission lines, or voltage sags due to

excessive current draw when a large inductive load is

turned on).

2: R should be suitably chosen so as to make

sure that the voltage drop across R does not

violate the device’s electrical specifications.

3: R1 should be suitably chosen so as to limit

any current flowing into MCLR from external

capacitor C, in the event of MCLR/VPP pin

breakdown due to Electrostatic Discharge

(ESD) or Electrical Overstress (EOS).

The BOR module allows selection of one of the

following voltage trip points (see Table 20-11):

17.4 Watchdog Timer (WDT)

17.6 Power-Saving Modes

There are two power-saving states that can be entered

through the execution of a special instruction, PWRSAV;

17.4.1

WATCHDOG TIMER OPERATION

The primary function of the Watchdog Timer (WDT) is

to reset the processor in the event of a software

malfunction. The WDT is a free-running timer which

runs off an on-chip RC oscillator, requiring no external

component. Therefore, the WDT timer will continue to

operate even if the main processor clock (e.g., the

crystal oscillator) fails.

these are Sleep and Idle.

The format of the PWRSAVinstruction is as follows:

PWRSAV <parameter>, where ‘parameter’ defines

Idle or Sleep mode.

17.6.1

SLEEP MODE

In Sleep mode, the clock to the CPU and peripherals is

shut down. If an on-chip oscillator is being used, it is

shut down.

17.4.2

ENABLING AND DISABLING

THE WDT

The Watchdog Timer can be “Enabled” or “Disabled”

only through a Configuration bit (FWDTEN) in the

Configuration register, FWDT.

The Fail-Safe Clock Monitor is not functional during

Sleep since there is no clock to monitor. However,

LPRC clock remains active if WDT is operational during

Sleep.

Setting FWDTEN = 1enables the Watchdog Timer. The

enabling is done when programming the device. By

default, after chip erase, FWDTEN bit = 1. Any device

programmer capable of programming dsPIC30F

devices allows programming of this and other

Configuration bits.

The brown-out protection circuit and the Low-Voltage

Detect circuit, if enabled, will remain functional during

Sleep.

The processor wakes up from Sleep if at least one of

the following conditions has occurred:

If enabled, the WDT will increment until it overflows or

“times out”. A WDT time-out will force a device Reset

(except during Sleep). To prevent a WDT time-out, the

user must clear the Watchdog Timer using a CLRWDT

instruction.

• any interrupt that is individually enabled and

meets the required priority level

• any Reset (POR, BOR and MCLR)

• WDT time-out

If a WDT times out during Sleep, the device will

wake-up. The WDTO bit in the RCON register will be

cleared to indicate a wake-up resulting from a WDT

time-out.

On waking up from Sleep mode, the processor will

restart the same clock that was active prior to entry into

Sleep mode. When clock switching is enabled, bits

COSC<2:0> will determine the oscillator source that

will be used on wake-up. If clock switch is disabled,

then there is only one system clock.

Setting FWDTEN

= 0 allows user software to

enable/disable the Watchdog Timer via the SWDTEN

(RCON<5>) control bit.

Note:

If a POR or BOR occurred, the selection of

the oscillator is based on the FOS<2:0>

and FPR<4:0> Configuration bits.

17.5 Low-Voltage Detect

The Low-Voltage Detect (LVD) module is used to

detect when the VDD of the device drops below a

threshold value, VLVD, which is determined by the

LVDL<3:0> bits (RCON<11:8>) and is thus user pro-

grammable. The internal voltage reference circuitry

requires a nominal amount of time to stabilize, and the

BGST bit (RCON<13>) indicates when the voltage

reference has stabilized.

If the clock source is an oscillator, the clock to the

device will be held off until OST times out (indicating a

stable oscillator). If PLL is used, the system clock is

held off until LOCK = 1 (indicating that the PLL is

stable). In either case, TPOR, TLOCK and TPWRT delays

are applied.

If EC, FRC, LPRC or ERC oscillators are used, then a

delay of TPOR (~ 10 μs) is applied. This is the smallest

delay possible on wake-up from Sleep.

In some devices, the LVD threshold voltage may be

applied externally on the LVDIN pin.

Moreover, if LP oscillator was active during Sleep and

LP is the oscillator used on wake-up, then the start-up

delay will be equal to TPOR. PWRT delay and OST

timer delay are not applied. In order to have the

smallest possible start-up delay when waking up from

Sleep, one of these faster wake-up options should be

selected before entering Sleep.

The LVD module is enabled by setting the LVDEN bit

(RCON<12>).

DS70139G-page 133

dsPIC30F2011/2012/3012/3013

Any interrupt that is individually enabled (using the

corresponding IE bit) and meets the prevailing priority

level will be able to wake-up the processor. The

processor will process the interrupt and branch to the

ISR. The Sleep Status bit in the RCON register is set

upon wake-up.

Any interrupt that is individually enabled (using IE bit)

and meets the prevailing priority level will be able to

wake-up the processor. The processor will process the

interrupt and branch to the ISR. The Idle Status bit in

the RCON register is set upon wake-up.

Any Reset other than POR will set the Idle Status bit.

On a POR, the Idle bit is cleared.

Note:

In spite of various delays applied (TPOR,

TLOCK and TPWRT), the crystal oscillator

(and PLL) may not be active at the end of

the time-out (e.g., for low-frequency

crystals). In such cases, if FSCM is

enabled, then the device will detect this as

a clock failure and process the clock failure

trap, the FRC oscillator will be enabled and

the user will have to re-enable the crystal

oscillator. If FSCM is not enabled, then the

device will simply suspend execution of

code until the clock is stable and will remain

in Sleep until the oscillator clock has

started.

If Watchdog Timer is enabled, then the processor will

wake-up from Idle mode upon WDT time-out. The Idle

and WDTO Status bits are both set.

Unlike wake-up from Sleep, there are no time delays

involved in wake-up from Idle.

17.7 Device Configuration Registers

The Configuration bits in each device Configuration

register specify some of the device modes and are

programmed by a device programmer, or by using the

In-Circuit Serial Programming™ (ICSP™) feature of

the device. Each device Configuration register is a

24-bit register, but only the lower 16 bits of each

register are used to hold configuration data. There are

five device Configuration registers available to the

user:

All Resets will wake-up the processor from Sleep

mode. Any Reset, other than POR, will set the Sleep

Status bit. In a POR, the Sleep bit is cleared.

If the Watchdog Timer is enabled, then the processor

will wake-up from Sleep mode upon WDT time-out. The

Sleep and WDTO Status bits are both set.

1. FOSC (0xF80000): Oscillator Configuration

Register

2. FWDT (0xF80002): Watchdog Timer

Configuration Register

17.6.2

IDLE MODE

3. FBORPOR (0xF80004): BOR and POR

Configuration Register

In Idle mode, the clock to the CPU is shut down while

peripherals keep running. Unlike Sleep mode, the clock

source remains active.

4. FGS (0xF8000A): General Code Segment

Configuration Register

Several peripherals have a control bit in each module

that allows them to operate during Idle.

5. FICD (0xF8000C): Debug Configuration

Register

LPRC Fail-Safe Clock remains active if clock failure

detect is enabled.

The placement of the Configuration bits is

automatically handled when you select the device in

your device programmer. The desired state of the

Configuration bits may be specified in the source code

(dependent on the language tool used), or through the

programming interface. After the device has been

programmed, the application software may read the

Configuration bit values through the table read

instructions. For additional information, please refer to

the Programming Specifications of the device.

The processor wakes up from Idle if at least one of the

following conditions has occurred:

• any interrupt that is individually enabled (IE bit is

‘1’) and meets the required priority level

• any Reset (POR, BOR, MCLR)

• WDT time-out

Upon wake-up from Idle mode, the clock is re-applied

to the CPU and instruction execution begins

immediately, starting with the instruction following the

PWRSAVinstruction.

Note:

If the code protection Configuration fuse

bits (FGS<GCP> and FGS<GWRP>)

have been programmed, an erase of the

entire code-protected device is only

possible at voltages VDD ≥ 4.5V.

dsPIC30F2011/2012/3012/3013

17.8 Peripheral Module Disable (PMD)

17.9 In-Circuit Debugger

Registers

When MPLAB^®ICD 2 is selected as a Debugger, the

In-Circuit Debugging functionality is enabled. This

function allows simple debugging functions when used

with MPLAB IDE. When the device has this feature

enabled, some of the resources are not available for

general use. These resources include the first 80 bytes

of Data RAM and two I/O pins.

The Peripheral Module Disable (PMD) registers

provide a method to disable a peripheral module by

stopping all clock sources supplied to that module.

When a peripheral is disabled via the appropriate PMD

control bit, the peripheral is in a minimum power

consumption state. The Control and Status registers

associated with the peripheral will also be disabled so

writes to those registers will have no effect and read

values will be invalid.

One of four pairs of Debug I/O pins may be selected by

the user using configuration options in MPLAB IDE.

These pin pairs are named EMUD/EMUC,

EMUD1/EMUC1,

EMUD3/EMUC3.

EMUD2/EMUC2

and

A peripheral module will only be enabled if both the

associated bit in the PMD register is cleared and the

peripheral is supported by the specific dsPIC DSC

variant. If the peripheral is present in the device, it is

enabled in the PMD register by default.

In each case, the selected EMUD pin is the

Emulation/Debug Data line, and the EMUC pin is the

Emulation/Debug Clock line. These pins will interface

to the MPLAB ICD 2 module available from Microchip.

The selected pair of Debug I/O pins is used by MPLAB

ICD 2 to send commands and receive responses, as

well as to send and receive data. To use the In-Circuit

Debugger function of the device, the design must

implement ICSP connections to MCLR, VDD, VSS,

PGC, PGD and the selected EMUDx/EMUCx pin pair.

Note 1: If a PMD bit is set, the corresponding

module is disabled after a delay of 1

instruction cycle. Similarly, if a PMD bit is

cleared, the corresponding module is

enabled after a delay of 1 instruction

cycle (assuming the module Control reg-

isters are already configured to enable

module operation).

This gives rise to two possibilities:

1. If EMUD/EMUC is selected as the Debug I/O pin

pair, then only a 5-pin interface is required, as

the EMUD and EMUC pin functions are multi-

plexed with the PGD and PGC pin functions in

all dsPIC30F devices.

2: In dsPIC30F2011, dsPIC30F3012 and

dsPIC30F2012 devices, the U2MD bit is

readable and writable and will be read as

‘1’ when set.

2. If

EMUD1/EMUC1,

EMUD2/EMUC2

or

EMUD3/EMUC3 is selected as the Debug I/O

pin pair, then a 7-pin interface is required, as the

EMUDx/EMUCx pin functions (x = 1, 2 or 3) are

not multiplexed with the PGD and PGC pin

functions.

Most bit-oriented instructions (including simple

rotate/shift instructions) have two operands:

18.0 INSTRUCTION SET SUMMARY

Note:

This data sheet summarizes features of

this group of dsPIC30F devices and is not

intended to be a complete reference

source. For more information on the CPU,

peripherals, register descriptions and

general device functionality, refer to the

“dsPIC30F Family Reference Manual”

(DS70046). For more information on the

Reference Manual” (DS70030).

• The W register (with or without an address

modifier) or file register (specified by the value of

‘Ws’ or ‘f’)

• The bit in the W register or file register

(specified by a literal value or indirectly by the

contents of register ‘Wb’)

The literal instructions that involve data movement may

use some of the following operands:

• A literal value to be loaded into a W register or file

register (specified by the value of ‘k’)

• The W register or file register where the literal

value is to be loaded (specified by ‘Wb’ or ‘f’)

The dsPIC30F instruction set adds many

enhancements to the previous PIC^®MCU instruction

sets, while maintaining an easy migration from

MCU instruction sets.

PIC

However, literal instructions that involve arithmetic or

logical operations use some of the following operands:

Most instructions are a single program memory word

(24 bits). Only three instructions require two program

memory locations.

• The first source operand which is a register ‘Wb’

without any address modifier

• The second source operand which is a literal

value

Each single-word instruction is a 24-bit word divided

into an 8-bit opcode which specifies the instruction

type, and one or more operands which further specify

the operation of the instruction.

• The destination of the result (only if not the same

as the first source operand) which is typically a

register ‘Wd’ with or without an address modifier

The instruction set is highly orthogonal and is grouped

into five basic categories:

The MACclass of DSP instructions may use some of the

following operands:

• Word or byte-oriented operations

• Bit-oriented operations

• Literal operations

• DSP operations

• Control operations

• The accumulator (A or B) to be used (required

operand)

• The W registers to be used as the two operands

• The X and Y address space prefetch operations

• The X and Y address space prefetch destinations

• The accumulator write-back destination

Table 18-1 shows the general symbols used in

describing the instructions.

The other DSP instructions do not involve any

multiplication, and may include:

The dsPIC30F instruction set summary in Table 18-2

lists all the instructions, along with the status flags

affected by each instruction.

• The accumulator to be used (required)

• The source or destination operand (designated as

Wso or Wdo, respectively) with or without an

address modifier

Most word or byte-oriented W register instructions

(including barrel shift instructions) have three

operands:

• The amount of shift specified by a W register ‘Wn’

or a literal value

• The first source operand which is typically a

register ‘Wb’ without any address modifier

The control instructions may use some of the following

operands:

• The second source operand which is typically a

register ‘Ws’ with or without an address modifier

• A program memory address

• The destination of the result which is typically a

register ‘Wd’ with or without an address modifier

• The mode of the table read and table write

instructions

However, word or byte-oriented file register instructions

have two operands:

• The file register specified by the value ‘f’

• The destination, which could either be the file

register ‘f’ or the W0 register, which is denoted as

‘WREG’

DS70139G-page 137

dsPIC30F2011/2012/3012/3013

All instructions are a single word, except for certain

double-word instructions, which were made

double-word instructions so that all the required

information is available in these 48 bits. In the second

word, the 8 MSbs are ‘0’s. If this second word is

executed as an instruction (by itself), it will execute as

a NOP.

RETURN/RETFIE instructions, which are single-word

instructions but take two or three cycles. Certain

instructions that involve skipping over the subsequent

instruction require either two or three cycles if the skip

is performed, depending on whether the instruction

being skipped is a single-word or two-word instruction.

Moreover, double-word moves require two cycles. The

double-word instructions execute in two instruction

cycles.

Most single-word instructions are executed in a single

instruction cycle, unless a conditional test is true or the

program counter is changed as a result of the

instruction. In these cases, the execution takes two

instruction cycles with the additional instruction

cycle(s) executed as a NOP. Notable exceptions are the

BRA (unconditional/computed branch), indirect

CALL/GOTO, all table reads and writes, and

dsPIC30F2011/2012/3012/3013

19.2 MPLAB C Compilers for Various

Device Families

19.5 MPLINK Object Linker/

MPLIB Object Librarian

The MPLAB C Compiler code development systems

are complete ANSI C compilers for Microchip’s PIC18,

PIC24 and PIC32 families of microcontrollers and the

dsPIC30 and dsPIC33 families of digital signal control-

lers. These compilers provide powerful integration

capabilities, superior code optimization and ease of

use.

The MPLINK Object Linker combines relocatable

objects created by the MPASM Assembler and the

MPLAB C18 C Compiler. It can link relocatable objects

from precompiled libraries, using directives from a

linker script.

The MPLIB Object Librarian manages the creation and

modification of library files of precompiled code. When

a routine from a library is called from a source file, only

the modules that contain that routine will be linked in

with the application. This allows large libraries to be

used efficiently in many different applications.

For easy source level debugging, the compilers provide

symbol information that is optimized to the MPLAB IDE

debugger.

19.3 HI-TECH C for Various Device

Families

The object linker/library features include:

• Efficient linking of single libraries instead of many

smaller files

The HI-TECH C Compiler code development systems

are complete ANSI C compilers for Microchip’s PIC

family of microcontrollers and the dsPIC family of digital

signal controllers. These compilers provide powerful

integration capabilities, omniscient code generation

and ease of use.

• Enhanced code maintainability by grouping

related modules together

• Flexible creation of libraries with easy module

listing, replacement, deletion and extraction

19.6 MPLAB Assembler, Linker and

Librarian for Various Device

Families

For easy source level debugging, the compilers provide

symbol information that is optimized to the MPLAB IDE

debugger.

The compilers include a macro assembler, linker, pre-

processor, and one-step driver, and can run on multiple

platforms.

MPLAB Assembler produces relocatable machine

code from symbolic assembly language for PIC24,

PIC32 and dsPIC devices. MPLAB C Compiler uses

the assembler to produce its object file. The assembler

generates relocatable object files that can then be

archived or linked with other relocatable object files and

archives to create an executable file. Notable features

of the assembler include:

19.4 MPASM Assembler

The MPASM Assembler is a full-featured, universal

macro assembler for PIC10/12/16/18 MCUs.

The MPASM Assembler generates relocatable object

files for the MPLINK Object Linker, Intel^®standard HEX

files, MAP files to detail memory usage and symbol

reference, absolute LST files that contain source lines

and generated machine code and COFF files for

debugging.

• Support for the entire device instruction set

• Support for fixed-point and floating-point data

• Command line interface

• Rich directive set

• Flexible macro language

The MPASM Assembler features include:

• Integration into MPLAB IDE projects

• MPLAB IDE compatibility

• User-defined macros to streamline

assembly code

• Conditional assembly for multi-purpose

source files

• Directives that allow complete control over the

assembly process

dsPIC30F2011/2012/3012/3013

19.7 MPLAB SIM Software Simulator

19.9 MPLAB ICD 3 In-Circuit Debugger

System

The MPLAB SIM Software Simulator allows code

development in a PC-hosted environment by simulat-

ing the PIC MCUs and dsPIC^®DSCs on an instruction

level. On any given instruction, the data areas can be

examined or modified and stimuli can be applied from

a comprehensive stimulus controller. Registers can be

logged to files for further run-time analysis. The trace

buffer and logic analyzer display extend the power of

the simulator to record and track program execution,

actions on I/O, most peripherals and internal registers.

MPLAB ICD 3 In-Circuit Debugger System is Micro-

chip's most cost effective high-speed hardware

debugger/programmer for Microchip Flash Digital Sig-

nal Controller (DSC) and microcontroller (MCU)

devices. It debugs and programs PIC^®Flash microcon-

trollers and dsPIC^®DSCs with the powerful, yet easy-

to-use graphical user interface of MPLAB Integrated

Development Environment (IDE).

The MPLAB ICD 3 In-Circuit Debugger probe is con-

nected to the design engineer's PC using a high-speed

USB 2.0 interface and is connected to the target with a

connector compatible with the MPLAB ICD 2 or MPLAB

REAL ICE systems (RJ-11). MPLAB ICD 3 supports all

MPLAB ICD 2 headers.

The MPLAB SIM Software Simulator fully supports

symbolic debugging using the MPLAB C Compilers,

and the MPASM and MPLAB Assemblers. The soft-

ware simulator offers the flexibility to develop and

debug code outside of the hardware laboratory envi-

ronment, making it an excellent, economical software

development tool.

19.10 PICkit 3 In-Circuit Debugger/

Programmer and

19.8 MPLAB REAL ICE In-Circuit

Emulator System

PICkit 3 Debug Express

The MPLAB PICkit 3 allows debugging and program-

ming of PIC^®and dsPIC^®Flash microcontrollers at a

most affordable price point using the powerful graphical

user interface of the MPLAB Integrated Development

Environment (IDE). The MPLAB PICkit 3 is connected

to the design engineer's PC using a full speed USB

interface and can be connected to the target via an

Microchip debug (RJ-11) connector (compatible with

MPLAB ICD 3 and MPLAB REAL ICE). The connector

uses two device I/O pins and the reset line to imple-

ment in-circuit debugging and In-Circuit Serial Pro-

gramming™.

MPLAB REAL ICE In-Circuit Emulator System is

Microchip’s next generation high-speed emulator for

Microchip Flash DSC and MCU devices. It debugs and

programs PIC^®Flash MCUs and dsPIC^®Flash DSCs

with the easy-to-use, powerful graphical user interface of

the MPLAB Integrated Development Environment (IDE),

included with each kit.

The emulator is connected to the design engineer’s PC

using a high-speed USB 2.0 interface and is connected

to the target with either a connector compatible with in-

circuit debugger systems (RJ11) or with the new high-

speed, noise tolerant, Low-Voltage Differential Signal

(LVDS) interconnection (CAT5).

The PICkit 3 Debug Express include the PICkit 3, demo

board and microcontroller, hookup cables and CDROM

with user’s guide, lessons, tutorial, compiler and

19.12 MPLAB PM3 Device Programmer

Also available are starter kits that contain everything

needed to experience the specified device. This usually

includes a single application and debug capability, all

on one board.

The MPLAB PM3 Device Programmer is a universal,

CE compliant device programmer with programmable

voltage verification at VDDMIN and VDDMAX for

maximum reliability. It features a large LCD display

(128 x 64) for menus and error messages and a modu-

lar, detachable socket assembly to support various

package types. The ICSP™ cable assembly is included

as a standard item. In Stand-Alone mode, the MPLAB

PM3 Device Programmer can read, verify and program

PIC devices without a PC connection. It can also set

code protection in this mode. The MPLAB PM3

connects to the host PC via an RS-232 or USB cable.

The MPLAB PM3 has high-speed communications and

optimized algorithms for quick programming of large

memory devices and incorporates an MMC card for file

storage and data applications.

20.0 ELECTRICAL CHARACTERISTICS

This section provides an overview of dsPIC30F electrical characteristics. Additional information will be provided in future

revisions of this document as it becomes available.

For detailed information about the dsPIC30F architecture and core, refer to the “dsPIC30F Family Reference Manual”

(DS70046).

Absolute maximum ratings for the dsPIC30F family are listed below. Exposure to these maximum rating conditions for

extended periods may affect device reliability. Functional operation of the device at these or any other conditions above

the parameters indicated in the operation listings of this specification is not implied.

Absolute Maximum Ratings^(†)

Ambient temperature under bias.............................................................................................................-40°C to +125°C

Storage temperature .............................................................................................................................. -65°C to +150°C

Voltage on any pin with respect to VSS (except VDD and MCLR) (Note 1)..................................... -0.3V to (VDD + 0.3V)

Voltage on VDD with respect to VSS ......................................................................................................... -0.3V to +5.5V

Voltage on MCLR with respect to VSS........................................................................................................ 0V to +13.25V

Maximum current out of VSS pin ...........................................................................................................................300 mA

Maximum current into VDD pin (Note 2)................................................................................................................250 mA

Input clamp current, IIK (VI < 0 or VI > VDD)..........................................................................................................±20 mA

Output clamp current, IOK (VO < 0 or VO > VDD)...................................................................................................±20 mA

Maximum output current sunk by any I/O pin..........................................................................................................25 mA

Maximum output current sourced by any I/O pin ....................................................................................................25 mA

Maximum current sunk by all ports .......................................................................................................................200 mA

Maximum current sourced by all ports (Note 2)....................................................................................................200 mA

Note 1: Voltage spikes below VSS at the MCLR/VPP pin, inducing currents greater than 80 mA, may cause latch-up.

Thus, a series resistor of 50-100Ωshould be used when applying a “low” level to the MCLR/VPP pin, rather

than pulling this pin directly to VSS.

2: Maximum allowable current is a function of device maximum power dissipation. See Table 20-2 for PDMAX.

^†NOTICE: Stresses above those listed under “Absolute Maximum Ratings” may cause permanent damage to the

device. This is a stress rating only and functional operation of the device at those or any other conditions above those

indicated in the operation listings of this specification is not implied. Exposure to maximum rating conditions for

extended periods may affect device reliability.

Note: All peripheral electrical characteristics are specified. For exact peripherals available on specific

devices, please refer to the dsPIC30F2011/2012/3012/3013 Sensor Family table on page 4 of

this data sheet.

2: The supply current is mainly a function of the operating voltage and frequency. Other factors such as I/O

pin loading and switching rate, oscillator type, internal code execution pattern and temperature also have

an impact on the current consumption. The test conditions for all IDD measurements are as follows: OSC1

driven with external square wave from rail to rail. All I/O pins are configured as Inputs and pulled to VDD.

MCLR = VDD, WDT, FSCM, LVD and BOR are disabled. CPU, SRAM, Program Memory and Data

“Max.” cycle time limit is “DC” (no clock) for all devices.

4: Measurements are taken in EC or ERC modes. The CLKO signal is measured on the OSC2 pin. CLKO is

low for the Q1-Q2 period (1/2 TCY) and high for the Q3-Q4 period (1/2 TCY).

Note 1: The A/D conversion result never decreases with an increase in the input voltage, and has no missing

codes.

2: Measurements taken with external VREF+ and VREF- used as the ADC voltage references.

Note 1: Because the sample caps will eventually lose charge, clock rates below 10 kHz can affect linearity

performance, especially at elevated temperatures.

2: tDPU is the time required for the ADC module to stabilize when it is turned on (ADCON1<ADON> = 1).

During this time the ADC result is indeterminate.
