Decoupling Capacitors
2.0
GUIDELINES FOR GETTING
STARTED WITH 16-BIT
DIGITAL SIGNAL
The use of decoupling capacitors on every pair of
power supply pins, such as VDD, VSS, AVDD and
AVSS is required.
CONTROLLERS
Consider the following criteria when using decoupling
capacitors:
Note:
This data sheet summarizes the features
of the dsPIC33FJ06GS101/X02 and
• Value and type of capacitor: Recommendation
of 0.1 μF (100 nF), 10-20V. This capacitor should
be a low-ESR and have resonance frequency in
the range of 20 MHz and higher. It is
dsPIC33FJ16GSX02/X04
family
of
devices. It is not intended to be a
comprehensive reference source. To
complement the information in this data
sheet, refer to the dsPIC33F Family
Reference Manual, which is available from
recommended that ceramic capacitors be used.
• Placement on the printed circuit board: The
decoupling capacitors should be placed as close
to the pins as possible. It is recommended to
place the capacitors on the same side of the
board as the device. If space is constricted, the
capacitor can be placed on another layer on the
PCB using a via; however, ensure that the trace
length from the pin to the capacitor is within
one-quarter inch (6 mm) in length.

2.1
Basic Connection Requirements
Getting started with the dsPIC33FJ06GS101/X02 and
dsPIC33FJ16GSX02/X04 family of 16-bit Digital Signal
Controllers (DSC) requires attention to a minimal set of
device pin connections before proceeding with
development. The following is a list of pin names, which
must always be connected:
• Handling high frequency noise: If the board is
experiencing high frequency noise, upward of
tens of MHz, add a second ceramic-type capacitor
in parallel to the above described decoupling
capacitor. The value of the second capacitor can
be in the range of 0.01 μF to 0.001 μF. Place this
second capacitor next to the primary decoupling
capacitor. In high-speed circuit designs, consider
implementing a decade pair of capacitances as
close to the power and ground pins as possible.
For example, 0.1 μF in parallel with 0.001 μF.
• All VDD and VSS pins
(see Section 2.2 “Decoupling Capacitors”)
• All AVDD and AVSS pins (regardless if ADC module
is not used)
(see Section 2.2 “Decoupling Capacitors”)
• VCAP/VDDCORE
(see Section 2.3 “Capacitor on Internal Voltage
Regulator (VCAP/VDDCORE)”)
• Maximizing performance: On the board layout
from the power supply circuit, run the power and
return traces to the decoupling capacitors first,
and then to the device pins. This ensures that the
decoupling capacitors are first in the power chain.
Equally important is to keep the trace length
between the capacitor and the power pins to a
minimum thereby reducing PCB track inductance.
• MCLR pin
(see Section 2.4 “Master Clear (MCLR) Pin”)
• PGECx/PGEDx pins used for In-Circuit Serial
Programming™ (ICSP™) and debugging purposes
(see Section 2.5 “ICSP Pins”)
• OSC1 and OSC2 pins when external oscillator
source is used
(see Section 2.6 “External Oscillator Pins”)

• Device Reset
VDD
• Device programming and debugging.
During device programming and debugging, the
resistance and capacitance that can be added to the
pin must be considered. Device programmers and
debuggers drive the MCLR pin. Consequently,
specific voltage levels (VIH and VIL) and fast signal
transitions must not be adversely affected. Therefore,
specific values of R and C will need to be adjusted
based on the application and PCB requirements.

2.2.1
TANK CAPACITORS
On boards with power traces running longer than six
inches in length, it is suggested to use a tank capacitor
for integrated circuits including DSCs to supply a local
power source. The value of the tank capacitor should
be determined based on the trace resistance that con-
nects the power supply source to the device, and the
maximum current drawn by the device in the applica-
tion. In other words, select the tank capacitor so that it
meets the acceptable voltage sag at the device. Typical
values range from 4.7 μF to 47 μF.

Capacitor on Internal Voltage
Regulator (VCAP/VDDCORE)
Note 1: R ≤ 10 kΩ is recommended. A suggested
starting value is 10 kΩ. Ensure that the
MCLR pin VIH and VIL specifications are met.
A low-ESR (< 5 Ohms) capacitor is required on the
VCAP/VDDCORE pin, which is used to stabilize the
voltage regulator output voltage. The VCAP/VDDCORE
pin must not be connected to VDD, and must have a
capacitor between 4.7 μF and 10 μF, 16V connected to
ground. The type can be ceramic or tantalum. Refer to
Section 24.0 “Electrical Characteristics” for
additional information.
2: R1 ≤ 470Ω will limit any current flowing into
MCLR from the external capacitor C, in the
event of MCLR pin breakdown, due to
Electrostatic Discharge (ESD) or Electrical
Overstress (EOS). Ensure that the MCLR pin
VIH and VIL specifications are met.
The placement of this capacitor should be close to the
VCAP/VDDCORE. It is recommended that the trace
length not exceed one-quarter inch (6 mm). Refer to
Section 21.2 “On-Chip Voltage Regulator” for
details.

ICSP Pins
2.6
External Oscillator Pins
The PGECx and PGEDx pins are used for In-Circuit
Serial Programming™ (ICSP™) and debugging
purposes. It is recommended to keep the trace length
between the ICSP connector and the ICSP pins on the
device as short as possible. If the ICSP connector is
expected to experience an ESD event, a series resistor
is recommended, with the value in the range of a few
tens of Ohms, not to exceed 100 Ohms.
Many DSCs have options for at least two oscillators: a
high-frequency primary oscillator and a low-frequency
secondary oscillator (refer to Section 8.0 “Oscillator
Configuration” for details).
The oscillator circuit should be placed on the same
side of the board as the device. Also, place the
oscillator circuit close to the respective oscillator pins,
not exceeding one-half inch (12 mm) distance
between them. The load capacitors should be placed
next to the oscillator itself, on the same side of the
board. Use a grounded copper pour around the
oscillator circuit to isolate them from surrounding
circuits. The grounded copper pour should be routed
directly to the MCU ground. Do not run any signal
traces or power traces inside the ground pour. Also, if
using a two-sided board, avoid any traces on the
other side of the board where the crystal is placed. A
suggested layout is shown in Figure 2-3.
Pull-up resistors, series diodes, and capacitors on the
PGECx and PGEDx pins are not recommended as they
will interfere with the programmer/debugger
communications to the device. If such discrete
components are an application requirement, they
should be removed from the circuit during program-
ming and debugging. Alternatively, refer to the AC/DC
characteristics and timing requirements information in
the respective device Flash programming specification
for information on capacitive loading limits and pin input
voltage high (VIH) and input low (VIL) requirements.

If your application needs to use certain A/D pins as
2.7
Oscillator Value Conditions on
Device Start-up
analog input pins during the debug session, the user
application must clear the corresponding bits in the
ADPCFG register during initialization of the ADC mod-
ule.
If the PLL of the target device is enabled and
configured for the device start-up oscillator, the
maximum oscillator source frequency must be limited
to 4 MHz < FIN < 8 MHz to comply with device PLL
start-up conditions. This means that if the external
oscillator frequency is outside this range, the
application must start up in the FRC mode first. The
default PLL settings after a POR with an oscillator
frequency outside this range will violate the device
operating speed.
When MPLAB ICD 2, ICD 3, or REAL ICE is used as a
programmer, the user application firmware must
correctly configure the ADPCFG register. Automatic
initialization of these registers is only done during
debugger operation. Failure to correctly configure the
register(s) will result in all A/D pins being recognized as
analog input pins, resulting in the port value being read
as a logic '0', which may affect user application func-
tionality.
Once the device powers up, the application firmware
can initialize the PLL SFRs, CLKDIV, and PLLDBF to a
suitable value, and then perform a clock switch to the
Oscillator + PLL clock source. Note that clock switching
must be enabled in the device Configuration word.
2.9
Unused I/Os
Unused I/O pins should be configured as outputs and
driven to a logic-low state.
2.8
Configuration of Analog and
Digital Pins During ICSP
Operations
Alternatively, connect a 1k to 10k resistor to VSS on
unused pins and drive the output to logic low.
2.10 Typical Application Connection
Examples
If MPLAB ICD 2, ICD 3 or REAL ICE is selected as a
debugger, it automatically initializes all of the A/D input
pins (ANx) as “digital” pins, by setting all bits in the
ADPCFG register.
Examples of typical application connections are shown
in Figure 2-4 through Figure 2-11.
The bits in the registers that correspond to the A/D pins
that are initialized by MPLAB ICD 2, ICD 3, or REAL
ICE, must not be cleared by the user application firm-
ware; otherwise, communication errors will result
between the debugger and the device.

3.1
Data Addressing Overview
3.0
CPU
The data space can be addressed as 32K words or
64 Kbytes and is split into two blocks, referred to as X
and Y data memory. Each memory block has its own
independent Address Generation Unit (AGU). The
MCU class of instructions operates solely through
the X memory AGU, which accesses the entire
memory map as one linear data space. Certain DSP
instructions operate through the X and Y AGUs to
support dual operand reads, which splits the data
address space into two parts. The X and Y data space
boundary is device-specific.
Note:
This data sheet summarizes the features
of the dsPIC33FJ06GS101/X02 and
dsPIC33FJ16GSX02/X04 families of
devices. It is not intended to be a
comprehensive reference source. To
complement the information in this data
sheet, refer to the “dsPIC33F Family
Reference Manual”, Section 2. “CPU”
(DS70204), which is available from the
Microchip web site (www.microchip.com).
The dsPIC33FJ06GS101/X02 and dsPIC33FJ16GSX02/
X04 CPU module has a 16-bit (data) modified Harvard
architecture with an enhanced instruction set, including
significant support for DSP. The CPU has a 24-bit
instruction word with a variable length opcode field. The
Program Counter (PC) is 23 bits wide and addresses up
to 4M x 24 bits of user program memory space. The
actual amount of program memory implemented varies
from device to device. A single-cycle instruction prefetch
mechanism is used to help maintain throughput and
provides predictable execution. All instructions execute in
a single cycle, with the exception of instructions that
change the program flow, the double-word move (MOV.D)
instruction and the table instructions. Overhead-free
program loop constructs are supported using the DOand
REPEAT instructions, both of which are interruptible at
any point.
Overhead-free circular buffers (Modulo Addressing
mode) are supported in both X and Y address spaces.
The Modulo Addressing removes the software
boundary checking overhead for DSP algorithms.
Furthermore, the X AGU circular addressing can be
used with any of the MCU class of instructions. The X
AGU also supports Bit-Reversed Addressing to greatly
simplify input or output data reordering for radix-2 FFT
algorithms.
The upper 32 Kbytes of the data space memory map
can optionally be mapped into program space at any
16K program word boundary defined by the 8-bit
Program Space Visibility Page (PSVPAG) register. The
program-to-data space mapping feature lets any
instruction access program space as if it were data
space.
The dsPIC33FJ06GS101/X02 and dsPIC33FJ16GSX02/
X04 devices have sixteen, 16-bit working registers in the
programmer’s model. Each of the working registers can
serve as a data, address or address offset register. The
sixteenth working register (W15) operates as a software
Stack Pointer (SP) for interrupts and calls.
3.2
DSP Engine Overview
The DSP engine features a high-speed, 17-bit by 17-bit
multiplier, 40-bit ALU, two 40-bit saturating
a
accumulators and a 40-bit bidirectional barrel shifter.
The barrel shifter is capable of shifting a 40-bit value up
to 16 bits, right or left, in a single cycle. The DSP
instructions operate seamlessly with all other
instructions and have been designed for optimal real-
time performance. The MACinstruction and other asso-
ciated instructions can concurrently fetch two data
operands from memory while multiplying two W
registers and accumulating and optionally saturating
the result in the same cycle. This instruction
functionality requires that the RAM data space be split
for these instructions and linear for all others. Data
space partitioning is achieved in a transparent and
flexible manner through dedicating certain working
registers to each address space.
There are two classes of instruction in the
dsPIC33FJ06GS101/X02 and dsPIC33FJ16GSX02/
X04 devices: MCU and DSP. These two instruction
classes are seamlessly integrated into a single CPU.
The instruction set includes many addressing modes
and is designed for optimum C compiler efficiency.
For most instructions, the dsPIC33FJ06GS101/X02
and dsPIC33FJ16GSX02/X04 is capable of execut-
ing a data (or program data) memory read, a work-
ing register (data) read, a data memory write and a
program (instruction) memory read per instruction
cycle. As a result, three parameter instructions can
be supported, allowing A + B = C operations to be
executed in a single cycle.
A block diagram of the CPU is shown in Figure 3-1,
and
the
programmer’s
model
for
the
dsPIC33FJ06GS101/X02 and dsPIC33FJ16GSX02/
X04 is shown in Figure 3-2.

The dsPIC33FJ06GS101/X02 and dsPIC33FJ16GSX02/
X04 supports 16/16 and 32/16 divide operations, both
fractional and integer. All divide instructions are iterative
operations. They must be executed within a REPEAT
loop, resulting in a total execution time of 19 instruction
cycles. The divide operation can be interrupted during
any of those 19 cycles without loss of data.
3.3
Special MCU Features
The dsPIC33FJ06GS101/X02 and dsPIC33FJ16GSX02/
X04 features a 17-bit by 17-bit single-cycle multiplier that
is shared by both the MCU ALU and DSP engine. The
multiplier can perform signed, unsigned and mixed sign
multiplication. Using a 17-bit by 17-bit multiplier for 16-bit
by 16-bit multiplication not only allows you to perform
mixed sign multiplication, it also achieves accurate
results for special operations, such as (-1.0) x (-1.0).
A 40-bit barrel shifter is used to perform up to a 16-bit
left or right shift in a single cycle. The barrel shifter can
be used by both MCU and DSP instructions.

DIVIDER
3.5
Arithmetic Logic Unit (ALU)
The divide block supports 32-bit/16-bit and 16-bit/16-bit
signed and unsigned integer divide operations with the
following data sizes:
The dsPIC33FJ06GS101/X02 and dsPIC33FJ16GSX02/
X04 ALU is 16 bits wide and is capable of addition,
subtraction, bit shifts and logic operations. Unless
otherwise mentioned, arithmetic operations are 2’s
complement in nature. Depending on the operation, the
ALU can affect the values of the Carry (C), Zero (Z),
Negative (N), Overflow (OV) and Digit Carry (DC) Status
bits in the SR register. The C and DC Status bits operate
as Borrow and Digit Borrow bits, respectively, for
subtraction operations.
• 32-bit signed/16-bit signed divide
• 32-bit unsigned/16-bit unsigned divide
• 16-bit signed/16-bit signed divide
• 16-bit unsigned/16-bit unsigned divide
The quotient for all divide instructions ends up in W0 and
the remainder in W1. 16-bit signed and unsigned DIV
instructions can specify any W register for both the 16-bit
The ALU can perform 8-bit or 16-bit operations,
depending on the mode of the instruction that is used.
Data for the ALU operation can come from the W
register array or data memory, depending on the
addressing mode of the instruction. Likewise, output
data from the ALU can be written to the W register array
or a data memory location.
divisor (Wn) and any
W register (aligned) pair
(W(m + 1):Wm) for the 32-bit dividend. The divide
algorithm takes one cycle per bit of divisor, so both 32-bit/
16-bit and 16-bit/16-bit instructions take the same
number of cycles to execute.
3.6
DSP Engine
Refer to the “dsPIC30F/33F Programmer’s Reference
Manual” (DS70157) for information on the SR bits
affected by each instruction.
The DSP engine consists of a high-speed, 17-bit x
17-bit multiplier, a barrel shifter and a 40-bit adder/
subtracter (with two target accumulators, round and
saturation logic).
The dsPIC33FJ06GS101/X02 and dsPIC33FJ16GSX02/
X04 CPU incorporates hardware support for both multipli-
cation and division. This includes a dedicated hardware
multiplier and support hardware for 16-bit-divisor division.
The dsPIC33FJ06GS101/X02 and dsPIC33FJ16GSX02/
X04 is a single-cycle instruction flow architecture; there-
fore, concurrent operation of the DSP engine with MCU
instruction flow is not possible. However, some MCU ALU
and DSP engine resources can be used concurrently by
the same instruction (for example, ED, EDAC).
3.5.1
MULTIPLIER
Using the high-speed, 17-bit x 17-bit multiplier of the
DSP engine, the ALU supports unsigned, signed or
mixed sign operation in several MCU multiplication
modes:
The DSP engine can also perform inherent
accumulator-to-accumulator operations that require no
additional data. These instructions are ADD, SUBand
NEG.
• 16-bit x 16-bit signed
• 16-bit x 16-bit unsigned
The DSP engine has options selected through bits in
the CPU Core Control register (CORCON), as listed
below:
• 16-bit signed x 5-bit (literal) unsigned
• 16-bit unsigned x 16-bit unsigned
• 16-bit unsigned x 5-bit (literal) unsigned
• 16-bit unsigned x 16-bit signed
• 8-bit unsigned x 8-bit unsigned
• Fractional or integer DSP multiply (IF)
• Signed or unsigned DSP multiply (US)
• Conventional or convergent rounding (RND)
• Automatic saturation on/off for ACCA (SATA)
• Automatic saturation on/off for ACCB (SATB)
• Automatic saturation on/off for writes to data
memory (SATDW)
• Accumulator Saturation mode selection
(ACCSAT)

3.6.1
MULTIPLIER
3.6.2.1
Adder/Subtracter, Overflow and
Saturation
The 17-bit 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-bit x 17-bit
multiplier/scaler is a 33-bit value that is sign-extended
to 40 bits. Integer data is inherently represented as a
signed 2’s complement value, where the Most
Significant bit (MSb) is defined as a sign bit. The range
of an N-bit 2’s complement integer is -2N-1 to 2N-1 – 1.
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).
• 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:
• For a 16-bit integer, the data range is -32768
(0x8000) to 32767 (0x7FFF) including 0.
• Overflow from bit 39: this is a catastrophic
overflow in which the sign of the accumulator is
destroyed.
• For a 32-bit integer, the data range is
-2,147,483,648 (0x8000 0000) to 2,147,483,647
(0x7FFF FFFF).
• 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.
When the multiplier is configured for fractional
multiplication, the data is represented as a 2’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 2’s
complement fraction with this implied radix point is -1.0
to (1 – 21-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 16 x 16 multiply operation generates a
The adder has an additional saturation block that
controls accumulator data saturation, if selected. It
uses the result of the adder, the Overflow Status bits
described
previously
and
the
SAT<A:B>
(CORCON<7:6>) and ACCSAT (CORCON<4>) mode
control bits to determine when and to what value to
saturate.
Six STATUS register bits support saturation and
overflow:
1.31 product that has a precision of 4.65661 x 10-10
.
The same multiplier is used to support the MCU
multiply instructions, which include integer 16-bit
signed, unsigned and mixed sign multiply operations.

The MUL instruction can be directed to use byte or

and

destination. For the ADDand LACinstructions, the data
to be accumulated or loaded can be optionally scaled
using 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 correspond-
ing Overflow Trap Flag Enable bits (OVATE, OVBTE) in
the INTCON1 register are set (refer to Section 7.0
“Interrupt Controller”). This allows the user applica-
tion to take immediate action, for example, to correct
system gain.

The SA and SB bits are modified each time data
passes through the adder/subtracter, but can only be
cleared by the user application. 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 saturation is not enabled, SA and SB
default to bit 39 overflow and thus, indicate that a cata-
strophic overflow has occurred. If the COVTE bit in the
INTCON1 register is set, SA and SB bits will generate
an arithmetic warning trap when saturation is disabled.
• W13, Register Direct:
The rounded contents of the non-target
accumulator are written into W13 as a
1.15 fraction.
• [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).
3.6.3.1
Round Logic
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). Programmers can 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 is useful for complex
number arithmetic, which typically uses both
accumulators.
The round logic is a combinational block that performs
a conventional (biased) or convergent (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 that 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 is simply discarded.
The device supports three Saturation and Overflow
modes:
Conventional rounding zero-extends bit 15 of the accu-
mulator and adds it to the ACCxH word (bits 16 through
31 of the accumulator).
• Bit 39 Overflow and Saturation:
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 accumu-
lator. The SA or SB bit is set and remains set until
cleared by the user application. This condition is
referred to as ‘super saturation’ and provides
protection against erroneous data or unexpected
algorithm problems (such as gain calculations).
• 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.
• Bit 31 Overflow and Saturation:
Convergent (or unbiased) rounding operates in the
same manner as conventional rounding, except when
ACCxL equals 0x8000. In this case, the Least
Significant bit (bit 16 of the accumulator) of ACCxH is
examined:
When bit 31 overflow and saturation occurs, the
saturation logic then loads the maximally positive
1.31 value (0x007FFFFFFF) or maximally nega-
tive 1.31 value (0x0080000000) into the target
accumulator. The SA or SB bit is set and remains
set until cleared by the user application. When
this Saturation mode is in effect, the guard bits are
not used, so the OA, OB or OAB bits are never
set.
• 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 removes any rounding bias that may
accumulate.
• 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 application. 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 3.6.3.2 “Data Space Write Saturation”). 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.
3.6.3
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:

3.6.3.2
Data Space Write Saturation
3.6.4
BARREL SHIFTER
In addition to adder/subtracter saturation, writes to data
space can 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 inputs
are combined and used to select the appropriate
1.15 fractional value as output to write to data space
memory.
The barrel shifter can perform 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:
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
and 31 for right shifts, and between bit positions 0 and
16 for left shifts.
• 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 Most Significant bit of the source (bit 39) is used to
determine the sign of the operand being tested.
If the SATDW bit in the CORCON register is not set, the
input data is always passed through unmodified under
all conditions.

addressable by a 24-bit value derived either from the
23-bit Program Counter (PC) during program execution,
or from table operation or data space remapping as
described in Section 4.6 “Interfacing Program and
Data Memory Spaces”.
Note:
This data sheet summarizes the features
of the dsPIC33FJ06GS101/X02 and
dsPIC33FJ16GSX02/X04 families of

complement the information in this data
sheet, refer to the “dsPIC33F Family
Reference Manual”, Section 4. “Program

User application access to the program memory space
is restricted to the lower half of the address range
(0x000000 to 0x7FFFFF). The exception is the use of
TBLRD/TBLWT operations, which use TBLPAG<7> to
permit access to the Configuration bits and Device ID
sections of the configuration memory space.

PROGRAM MEMORY
ORGANIZATION
4.1.2
INTERRUPT AND TRAP VECTORS
All dsPIC33FJ06GS101/X02 and dsPIC33FJ16GSX02/
X04 devices reserve the addresses between 0x00000
and 0x000200 for hard-coded program execution vectors.
A hardware Reset vector is provided to redirect code exe-
cution from the default value of the PC on device Reset to
the actual start of code. A GOTO instruction is
programmed by the user application at 0x000000, with
the actual address for the start of code at 0x000002.
The program memory space is organized in word-
addressable blocks. Although it is treated as 24 bits
wide, it is more appropriate to think of each address of
the program memory as a lower and upper word, with
the upper byte of the upper word being unimplemented.
The lower word always has an even address, while the
upper word has an odd address (see Figure 4-2).
The dsPIC33FJ06GS101/X02 and dsPIC33FJ16GSX02/
X04 devices also have two interrupt vector tables, located
from 0x000004 to 0x0000FF and 0x000100 to 0x0001FF.
These vector tables allow each of the device interrupt
sources to be handled by separate Interrupt Service
Routines (ISRs). A more detailed discussion of the
interrupt vector tables is provided in Section 7.1
“Interrupt Vector Table”.
Program memory addresses are always word-aligned
on the lower word, and addresses are incremented or
decremented by two during the code execution. This
arrangement provides compatibility with data memory
space addressing and makes data in the program

All word accesses must be aligned to an even address.
4.2
Data Address Space
Misaligned word data fetches are not supported, so
care must be taken when mixing byte and word
operations, or translating from 8-bit MCU code. If a
misaligned read or write is attempted, an address error
trap is generated. If the error occurred on a read, the
instruction underway is completed. If the error 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 application to examine
the machine state prior to execution of the address
Fault.
The
dsPIC33FJ06GS101/X02
and
dsPIC33FJ16GSX02/X04 CPU has a separate, 16-bit-
wide data memory space. The data space is accessed
using separate Address Generation Units (AGUs) for
read and write operations. The data memory maps is
shown in Figure 4-3.
All Effective Addresses (EAs) in the data memory space
are 16 bits wide and point to bytes within the data space.
This arrangement gives a data space address range of
64 Kbytes or 32K words. The lower half of the data
memory space (that is, when EA<15> = 0) is used for
implemented memory addresses, while the upper half
(EA<15> = 1) is reserved for the Program Space
Visibility area (see Section 4.6.3 “Reading Data From
Program Memory Using Program Space Visibility”).
All byte loads into any W register are loaded into the
Least Significant Byte. The Most Significant Byte is not
modified.
A sign-extend instruction (SE) is provided to allow user
applications to translate 8-bit signed data to 16-bit
signed values. Alternatively, for 16-bit unsigned data,
user applications can clear the MSB of any W register
by executing a zero-extend (ZE) instruction on the
appropriate address.
dsPIC33FJ06GS101/X02 and dsPIC33FJ16GSX02/
X04 devices implement up to 30 Kbytes of data
memory. Should an EA point to a location outside of
this area, an all-zero word or byte will be returned.
4.2.1
DATA SPACE WIDTH
4.2.3
SFR SPACE
The data memory space is organized in byte
addressable, 16-bit wide blocks. Data is aligned in data
memory and registers as 16-bit words, but all data
space EAs resolve to bytes. The Least Significant
Bytes (LSBs) of each word have even addresses, while
the Most Significant Bytes (MSBs) have odd
addresses.
The first 2 Kbytes of the near data space, from 0x0000
to 0x07FF, is primarily occupied by Special Function
Registers (SFRs). These are used by the
dsPIC33FJ06GS101/X02 and dsPIC33FJ16GSX02/
X04 core and peripheral modules for controlling the
operation of the device.
SFRs are distributed among the modules that they
control, and are generally grouped together by module.
Much of the SFR space contains unused addresses;
these are read as ‘0’.

DATA MEMORY ORGANIZATION
AND ALIGNMENT
To maintain backward compatibility with PIC® MCU
devices and improve data space memory usage
Note:
The actual set of peripheral features and
interrupts varies by the device. Refer to
the corresponding device tables and
pinout diagrams for device-specific
information.
efficiency,
the
dsPIC33FJ06GS101/X02
and
dsPIC33FJ16GSX02/X04 instruction set supports both
word and byte operations. As a consequence of byte
accessibility, all effective address calculations are
internally scaled to step through word-aligned memory.
For example, the core recognizes that Post-Modified
Register Indirect Addressing mode [Ws++] that results
in a value of Ws + 1 for byte operations and Ws + 2 for
word operations.
4.2.4
NEAR DATA SPACE
The 8-Kbyte area between 0x0000 and 0x1FFF is
referred to as the near data space. Locations in this
space are directly addressable via a 13-bit absolute
address field within all memory direct instructions.
Additionally, the whole data space is addressable using
MOV instructions, which support Memory Direct
Addressing mode with a 16-bit address field, or by
using Indirect Addressing mode using a working
register as an Address Pointer.
Data byte reads will 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 data path. 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 that
matches the byte address.

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.
4.2.5
X AND Y DATA SPACES
The core has two data spaces, X and Y. These 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. This feature allows certain
instructions to concurrently fetch two words from RAM,
thereby enabling efficient execution of DSP algorithms,
such as Finite Impulse Response (FIR) filtering and
Fast Fourier Transform (FFT).
Both the X and Y data spaces support Modulo
Addressing mode for all instructions, subject to
addressing mode restrictions. Bit-Reversed Addressing
mode is only supported for writes to X data space.
All data memory writes, including in DSP instructions,
view data space as combined X and Y address space.
The boundary between the X and Y data spaces is
device-dependent and is not user-programmable.
The X data space is used by all instructions and
supports all addressing modes. X data space has
separate read and write data buses. The X read data
bus is the read data path for all instructions that view
data space as combined X and Y address space. It is
also the X data prefetch path for the dual operand DSP
instructions (MACclass).
All effective addresses are 16 bits wide and point to
bytes within the data space. Therefore, the data space
address range is 64 Kbytes, or 32K words, though the
implemented memory locations vary by device.

SOFTWARE STACK
4.3
Instruction Addressing Modes
In addition to its use as a working register, the W15
register in the dsPIC33FJ06GS101/X02 and
dsPIC33FJ16GSX02/X04 devices is also used as a
software Stack Pointer. The Stack Pointer always
points to the first available free word and grows from
lower to higher addresses. It predecrements for stack
pops and post-increments for stack pushes, as shown
in Figure 4-6. For a PC push during any CALLinstruc-
tion, the MSb of the PC is zero-extended before the
push, ensuring that the MSb is always clear.
The addressing modes shown in Table 4-48 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 differ from those in the other instruction
types.
4.3.1
FILE REGISTER INSTRUCTIONS
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.
Note:
A PC push during exception processing
concatenates the SRL register to the MSb
of the PC prior to the push.
The Stack Pointer Limit register (SPLIM) associated
with the Stack Pointer sets an upper address boundary
for the stack. 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.
4.3.2
MCU INSTRUCTIONS
Whenever an EA is generated using W15 as a source
or destination pointer, the resulting address is
compared with the value in SPLIM. If the contents of
the Stack Pointer (W15) and the SPLIM register are
equal and a push operation is performed, a stack error
trap will not occur. The stack error trap will occur on a
subsequent push operation. For example, to cause a
stack error trap when the stack grows beyond address
0x1000 in RAM, initialize the SPLIM with the value
0x0FFE.
The three-operand MCU instructions are of the form:
Operand 3 = Operand 1 <function> Operand 2
where Operand 1 is always a working register (that is,
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 a data memory
location. The following addressing modes are
supported by MCU instructions:
Similarly, a Stack Pointer underflow (stack error) trap is
generated when the Stack Pointer address is found to
be less than 0x0800. This prevents the stack from
interfering with the Special Function Register (SFR)
space.
• Register Direct
• Register Indirect
• Register Indirect Post-Modified
• Register Indirect Pre-Modified
• 5-Bit or 10-Bit Literal
A write to the SPLIM register should not be immediately
followed by an indirect read operation using W15.
Note:
Not all instructions support all the
addressing modes given above. Individual
instructions can support different subsets
of these addressing modes.

MOVE AND ACCUMULATOR
INSTRUCTIONS
4.3.4
MACINSTRUCTIONS
The dual source operand DSP instructions (CLR, ED,
EDAC, MAC, MPY, MPY.N, MOVSACand MSC), also referred
to as MACinstructions, use a simplified set of addressing
modes to allow the user application to effectively
manipulate the data pointers through register indirect
tables.
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.
The two-source operand prefetch registers must be
members of the set {W8, W9, W10, W11}. For data
reads, W8 and W9 are always directed to the X RAGU,
and 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.
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 by both source and
destination (but typically only used by
one).
Note:
Register Indirect with Register Offset
Addressing mode is available only for W9
(in X space) and W11 (in Y space).
In summary, the following addressing modes are
supported by move and accumulator instructions:
In summary, the following addressing modes are
• Register Direct
supported by the MACclass of instructions:
• Register Indirect
• Register Indirect
• Register Indirect Post-modified
• Register Indirect Pre-modified
• Register Indirect with Register Offset (Indexed)
• Register Indirect with Literal Offset
• 8-Bit Literal
• Register Indirect Post-Modified by 2
• Register Indirect Post-Modified by 4
• Register Indirect Post-Modified by 6
• Register Indirect with Register Offset (Indexed)
• 16-Bit Literal
4.3.5
OTHER INSTRUCTIONS
Note:
Not all instructions support all the
addressing modes given above. Individual
instructions may support different subsets
of these addressing modes.
Besides the addressing modes outlined previously, 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 DISIinstruction 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.

Modulo Addressing
Note:
Y
space Modulo Addressing EA
calculations assume word-sized data (LSb
of every EA is always clear).
Modulo Addressing mode is a method used to provide
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.
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).
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.
4.4.2
W ADDRESS REGISTER
SELECTION
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 the
registers that will operate with Modulo Addressing:
In general, any particular circular buffer can be
configured to operate in only one direction as there are
certain restrictions on the buffer start address (for
incrementing buffers), or end address (for
decrementing buffers), based upon the direction of the
buffer.
• If XWM = 15, X RAGU and X WAGU Modulo
Addressing is disabled.
• If YWM = 15, Y AGU Modulo Addressing is
disabled.
The X Address Space Pointer W register (XWM), to
which Modulo Addressing is to be applied, is stored in
MODCON<3:0> (see Table 4-1). 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 only exception to the usage restrictions is for
buffers that have a power-of-two length. As these
buffers satisfy the start and end address criteria, they
can operate in a bidirectional mode (that is, address
boundary checks are performed on both the lower and
upper address boundaries).
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>.
4.4.1
START AND END ADDRESS
The Modulo Addressing scheme requires that a
starting and ending address be specified and loaded
into the 16-bit Modulo Buffer Address registers:
XMODSRT, XMODEND, YMODSRT and YMODEND
(see Table 4-1).

If the length of a bit-reversed buffer is M = 2N bytes,
the last ‘N’ bits of the data buffer start address must
be zeros.
4.4.3
MODULO ADDRESSING
APPLICABILITY
Modulo Addressing can be applied to the Effective
Address (EA) calculation associated with any W
register. Address boundaries check for addresses
equal to:
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.
• The upper boundary addresses for incrementing
buffers
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.
• The lower boundary addresses for decrementing
buffers
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 can, therefore, jump beyond
boundaries and still be adjusted correctly.
When enabled, Bit-Reversed Addressing is executed
only for Register Indirect with Pre-Increment or Post-
Increment Addressing and word-sized data writes. It
will not function for any other addressing mode or for
byte-sized data, and 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 Regis-
ter Indirect Addressing mode is ignored. In addition, as
word-sized data is a requirement, the LSb of the EA is
ignored (and always clear).
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 effective address.
When an address offset (such as
[W7 + W2]) is used, Modulo Addressing
correction is performed but the contents of
the register remain unchanged.
Note:
Modulo Addressing and Bit-Reversed
Addressing should not be enabled
together. If an application attempts to do so,
Bit-Reversed Addressing will assume
priority when active for the X WAGU and X
WAGU; Modulo Addressing will be dis-
abled. However, Modulo Addressing will
continue to function in the X RAGU.
4.5
Bit-Reversed Addressing
Bit-Reversed Addressing mode is intended to simplify
data re-ordering for radix-2 FFT algorithms. It is
supported by the X AGU for data writes only.
The modifier, which can 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.
If Bit-Reversed Addressing has already been enabled
by setting the BREN (XBREV<15>) bit, 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.
4.5.1
BIT-REVERSED ADDRESSING
IMPLEMENTATION
Bit-Reversed Addressing mode is enabled in any of
these situations:
• BWM bits (W register selection) in the MODCON
register are any value other than 15 (the stack
cannot be accessed using Bit-Reversed
Addressing)
• The BREN bit is set in the XBREV register
• The addressing mode used is Register Indirect
with Pre-Increment or Post-Increment

4.6.1
ADDRESSING PROGRAM SPACE
4.6
Interfacing Program and Data
Memory Spaces
Since the address ranges for the data and program
spaces are 16 and 24 bits, respectively, a method is
needed to create a 23-bit or 24-bit program address
from 16-bit data registers. The solution depends on the
interface method to be used.
The dsPIC33FJ06GS101/X02 and dsPIC33FJ16GSX02/
X04 architecture uses a 24-bit-wide program space and a
16-bit-wide data space. The architecture is also a modi-
fied Harvard scheme, meaning that data can also be
present in the program space. To use this data success-
fully, it must be accessed in a way that preserves the
alignment of information in both spaces.
For table operations, the 8-bit Table Page register
(TBLPAG) is used to define a 32K word region within
the program space. This is concatenated with a 16-bit
EA to arrive at a full 24-bit program space address. In
this format, the Most Significant bit of TBLPAG is used
to determine if the operation occurs in the user memory
(TBLPAG<7> = 0) or the configuration memory
(TBLPAG<7> = 1).
Aside from normal execution, the dsPIC33FJ06GS101/
X02 and dsPIC33FJ16GSX02/X04 architecture
provides two methods by which program space can be
accessed during operation:
• Using table instructions to access individual bytes
or words anywhere in the program space
For remapping operations, the 8-bit Program Space
Visibility Register (PSVPAG) is used to define a
16K word page in the program space. When the Most
Significant bit of the EA is ‘1’, PSVPAG is concatenated
with the lower 15 bits of the EA to form a 23-bit program
space address. Unlike table operations, this limits
remapping operations strictly to the user memory area.
• Remapping a portion of the program space into
the data space (Program Space Visibility)
Table instructions allow an application to read or write
to small areas of the program memory. This capability
makes the method ideal for accessing data tables that
need to be updated periodically. It also allows access
to all bytes of the program word. The remapping
method allows an application to access a large block of
data on a read-only basis, which is ideal for look ups
from a large table of static data. The application can
only access the least significant word of the program
word.
Table 4-50 and Figure 4-9 show how the program EA is
created for table operations and remapping accesses
from the data EA. Here, P<23:0> refers to a program
space word, and D<15:0> refers to a data space word.

- In Byte mode, either the upper or lower byte
of the lower program word is mapped to the
lower byte of a data address. The upper byte
is selected when byte select is ‘1’; the lower
byte is selected when it is ‘0’.
4.6.2
DATA ACCESS FROM PROGRAM
MEMORY USING TABLE
INSTRUCTIONS
The TBLRDL and TBLWTL instructions offer a direct
method of reading or writing the lower word of any
address within the program space without going
through data space. The TBLRDH and TBLWTH
instructions are the only method to read or write the
upper 8 bits of a program space word as data.
• TBLRDH (Table Read High):
- In Word mode, this instruction maps the entire
upper word of a program address (P<23:16>)
to a data address. Note that D<15:8>, the
‘phantom byte’, 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
wide word address spaces, residing side by side, each
with the same address range. TBLRDL and TBLWTL
access the space that contains the least significant
data word. TBLRDHand TBLWTHaccess the space that
contains the upper data byte.
- In Byte mode, this instruction maps the upper
or lower byte of the program word to D<7:0>
of the data address, in the TBLRDL
instruction. The data is always ‘0’ when the
upper ‘phantom’ byte is selected (Byte
Select = 1).
Similarly, two table instructions, TBLWTHand TBLWTL,
are used to write individual bytes or words to a program
space address. The details of their operation are
explained in Section 5.0 “Flash Program Memory”.
Two table instructions are provided to move byte or
word-sized (16-bit) data to and from program space.
Both function as either byte or word operations.
For all table operations, the area of program memory
space to be accessed is determined by the Table Page
register (TBLPAG). TBLPAG covers the entire program
memory space of the device, including user and
configuration spaces. When TBLPAG<7> = 0, the table
page is located in the user memory space. When
TBLPAG<7> = 1, the page is located in configuration
space.
• TBLRDL(Table Read Low):
- In Word mode, this instruction maps the
lower word of the program space location
(P<15:0>) to a data address (D<15:0>).

24-bit program word are used to contain the data. The
upper 8 bits of any program space location used as
data should be programmed with ‘1111 1111’ or
‘0000 0000’ to force a NOP. This prevents possible
issues should the area of code ever be accidentally
executed.
4.6.3
READING DATA FROM PROGRAM
MEMORY USING PROGRAM SPACE
VISIBILITY
The upper 32 Kbytes of data space may optionally be
mapped into any 16K word page of the program space.
This option provides transparent access to stored
constant data from the data space without the need to
use special instructions (such as TBLRDL/H).
Note:
PSV access is temporarily disabled during
table reads/writes.
Program space access through the data space occurs
if the Most Significant bit of the data space EA is ‘1’ and
program space visibility is enabled by setting the PSV
bit in the Core Control register (CORCON<2>). The
location of the program memory space to be mapped
into the data space is determined by the Program
Space Visibility Page register (PSVPAG). This 8-bit
register defines any one of 256 possible pages of
16K words in program space. In effect, PSVPAG
functions as the upper 8 bits of the program memory
address, with the 15 bits of the EA functioning as the
lower bits. By incrementing the PC by 2 for each
program memory word, the lower 15 bits of data space
addresses directly map to the lower 15 bits in the
corresponding program space addresses.
For operations that use PSV and are executed outside
aREPEATloop, theMOVand MOV.Dinstructions require
one instruction cycle in addition to the specified
execution time. All other instructions require two
instruction cycles in addition to the specified execution
time.
For operations that use PSV, and are executed inside
a REPEATloop, these instances require two instruction
cycles in addition to the specified execution time of the
instruction:
• 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
Data reads to this area add a cycle to the instruction
being executed, since two program memory fetches
are required.
Any other iteration of the REPEAT loop will allow the
instruction using PSV to access data, to execute in a
single cycle.
Although each data space address 8000h and higher
maps directly into a corresponding program memory
address (see Figure 4-11), only the lower 16 bits of the

RTSP is accomplished using TBLRD (table read) and
TBLWT (table write) instructions. With RTSP, the user
application can write program memory data, either in
blocks or ‘rows’ of 64 instructions (192 bytes) at a time,
or a single program memory word, and erase program
memory in blocks or ‘pages’ of 512 instructions
(1536 bytes) at a time.
5.1
Table Instructions and Flash
Programming
The dsPIC33FJ06GS101/X02 and dsPIC33FJ16GSX02/
X04 devices contain internal Flash program memory for
storing and executing application code. The memory is
readable, writable and erasable during normal operation
over the entire VDD range.
Regardless of the method used, all programming of
Flash memory is done with the table read and table
write instructions. These allow direct read and write
access to the program memory space from the data
memory while the device is in normal operating mode.
The 24-bit target address in the program memory is
formed using bits<7:0> of the TBLPAG register and the
Effective Address (EA) from a W register specified in
the table instruction, as shown in Figure 5-1.
Flash memory can be programmed in two ways:
• In-Circuit Serial Programming™ (ICSP™)
programming capability
• Run-Time Self-Programming (RTSP)
The TBLRDLand the TBLWTLinstructions are used to
read or write to bits<15:0> of program memory.
TBLRDLand TBLWTLcan access program memory in
both Word and Byte modes.
ICSP allows
a
dsPIC33FJ06GS101/X02 and
dsPIC33FJ16GSX02/X04 device to be serially
programmed while in the end application circuit. This is
done with two lines for programming clock and
programming data (one of the alternate programming
pin pairs: PGECx/PGEDx, 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 digital
The TBLRDHand TBLWTHinstructions are used to read
or write to bits<23:16> of program memory. TBLRDH

RTSP Operation
5.3
Programming Operations
The dsPIC33FJ06GS101/X02 and dsPIC33FJ16GSX02/
X04 Flash program memory array is organized into rows
of 64 instructions or 192 bytes. RTSP allows the user
application to erase a page of memory, which consists of
eight rows (512 instructions) at a time, and to program
one row or one word at a time. Table 24-12 shows typical
erase and programming times. The 8-row erase pages
and single row write rows are edge-aligned from the
beginning of program memory, on boundaries of
1536 bytes and 192 bytes, respectively.
A complete programming sequence is necessary for
programming or erasing the internal Flash in RTSP
mode. The processor stalls (waits) until the
programming operation is finished.
The programming time depends on the FRC accuracy
(see Table 24-20) and the value of the FRC Oscillator
Tuning register (see Register 8-4). Use the following
formula to calculate the minimum and maximum values
for the Row Write Time, Page Erase Time, and Word
Write Cycle Time parameters (see Table 24-12).
The program memory implements holding buffers that
can contain 64 instructions of programming data. Prior
to the actual programming operation, the write data
must be loaded into the buffers sequentially. The
instruction words loaded must always be from a group
of 64 boundary.
EQUATION 5-1:
PROGRAMMING TIME

-------------------------------------------------------------------------------------------------------------------------

For example, if the device is operating at +125°C,
the FRC accuracy will be ±5%. If the TUN<5:0> bits
(see Register 8-4) are set to ‘b111111, the
Minimum Row Write Time is:
The basic sequence for RTSP programming is to set up
a Table Pointer, then do a series of TBLWTinstructions
to load the buffers. Programming is performed by
setting the control bits in the NVMCON register. A total
of 64 TBLWTL and TBLWTH instructions are required
to load the instructions.

Control Registers
Two SFRs are used to read and write the program
Flash memory: NVMCON and NVMKEY.
The NVMCON register (Register 5-1) controls which
blocks are to be erased, which memory type is to be
programmed and the start of the programming cycle.
NVMKEY is a write-only register that is used for write
protection. To start a programming or erase sequence,
the user application must consecutively write 0x55 and
0xAA to the NVMKEY register. Refer to Section 5.3
“Programming Operations” for further details.

a) Set the NVMOP bits to ‘0001’ to configure
for row programming. Clear the ERASE bit
and set the WREN bit.
b) Write 0x55 to NVMKEY.
c) Write 0xAA to NVMKEY.
1. Read eight rows of program memory
(512 instructions) and store in data RAM.
d) Set the WR bit. The programming cycle
begins and the CPU stalls for the duration of
the write cycle. When the write to Flash
memory is done, the WR bit is cleared
automatically.
2. Update the program data in RAM with the
desired new data.
3. Erase the block (see Example 5-1):
a) Set the NVMOP bits (NVMCON<3:0>) to
‘0010’ to configure for block erase. Set the
ERASE (NVMCON<6>) and WREN
(NVMCON<14>) bits.
6. Repeat steps 4 and 5, using the next available
64 instructions from the block in data RAM by
incrementing the value in TBLPAG, until all
512 instructions are written back to Flash memory.
b) Write the starting address of the page to be
erased into the TBLPAG and W registers.
For protection against accidental operations, the write
initiate sequence for NVMKEY must be used to allow
any erase or program operation to proceed. After the
programming command has been executed, the user
application must wait for the programming time until
programming is complete. The two instructions
following the start of the programming sequence
should be NOPs, as shown in Example 5-3.
c) Write 0x55 to NVMKEY.
d) Write 0xAA to NVMKEY.
e) Set the WR bit (NVMCON<15>). The erase
cycle begins and the CPU stalls for the
duration of the erase cycle. When the erase is
done, the WR bit is cleared automatically.

signal active. On system Reset, some of the registers
associated with the CPU and peripherals are forced to
a known Reset state and some are unaffected.
Note:
This data sheet summarizes the features
of the dsPIC33FJ06GS101/X02 and
dsPIC33FJ16GSX02/X04 families of
devices. It is not intended to be a
comprehensive reference source. To
complement the information in this data
sheet, refer to the “dsPIC33F Family
Reference Manual”, Section 8. “Reset”
(DS70192), which is available from the
Microchip web site (www.microchip.com).
Note:
Refer to the specific peripheral section or
Section 3.0 “CPU” of this data sheet for
register Reset states.
All types of device Reset sets a corresponding status
bit in the RCON register to indicate the type of Reset
(see Register 6-1).
A POR clears all the bits, except for the POR bit
(RCON<0>), that are set. The user application can set
or clear any bit at any time during code execution. The
RCON bits only serve as status bits. Setting a particular
Reset status bit in software does not cause a device
Reset to occur.
The Reset module combines all Reset sources and
controls the device Master Reset Signal, SYSRST. The
following is a list of device Reset sources:
• POR: Power-on Reset
• BOR: Brown-out Reset
The RCON register also has other bits associated with
the Watchdog Timer and device power-saving states.
The function of these bits is discussed in other sections
of this manual.
• MCLR: Master Clear Pin Reset
• SWR: Software RESETInstruction
• WDTO: Watchdog Timer Reset
• CM: Configuration Mismatch Reset
• TRAPR: Trap Conflict Reset
• IOPUWR: Illegal Condition Device Reset
Note:
The status bits in the RCON register
should be cleared after they are read so
that the next RCON register value after a
device Reset is meaningful.
- Illegal Opcode Reset
- Uninitialized W Register Reset
- Security Reset

2. BOR Reset: The on-chip voltage regulator has
a BOR circuit that keeps the device in Reset
until VDD crosses the VBOR threshold and the
delay, TBOR, has elapsed. The delay, TBOR,
ensures that the voltage regulator output
becomes stable.
6.1
System Reset
The dsPIC33FJ06GS101/X02 and dsPIC33FJ16GSX02/
X04 families of devices have two types of Reset:
• Cold Reset
• Warm Reset
3. PWRT Timer: The programmable power-up
timer continues to hold the processor in Reset
for a specific period of time (TPWRT) after a
BOR. The delay TPWRT ensures that the system
power supplies have stabilized at the
appropriate level for full-speed operation. After
the delay, TPWRT, has elapsed, the SYSRST
becomes inactive, which in turn enables the
selected oscillator to start generating clock
cycles.
A cold Reset is the result of a Power-on Reset (POR)
or a Brown-out Reset (BOR). On a cold Reset, the
FNOSC Configuration bits in the FOSC Configuration
register select the device clock source.
A warm Reset is the result of all the other Reset
sources, including the RESET instruction. On warm
Reset, the device will continue to operate from the
current clock source as indicated by the Current
Oscillator Selection (COSC<2:0>) bits in the Oscillator
Control (OSCCON<14:12>) register.
4. Oscillator Delay: The total delay for the clock to
be ready for various clock source selections is
given in Table 6-1. Refer to Section 8.0
“Oscillator Configuration”for moreinformation.
The device is kept in a Reset state until the system
power supplies have stabilized at appropriate levels
and the oscillator clock is ready. The sequence in
which this occurs is detailed below and is shown in
Figure 6-2.
5. When the oscillator clock is ready, the processor
begins execution from location 0x000000. The
user application programs a GOTOinstruction at
the Reset address, which redirects program
execution to the appropriate start-up routine.
1. POR Reset: A POR circuit holds the device in
Reset when the power supply is turned on. The
POR circuit is active until VDD crosses the VPOR
threshold and the delay, TPOR, has elapsed.
6. The Fail-Safe Clock Monitor (FSCM), if enabled,
begins to monitor the system clock when the
system clock is ready and the delay, TFSCM,
elapsed.

Brown-out Reset (BOR) and
Power-up Timer (PWRT)
Note: When the device exits the Reset
condition (begins normal operation), the
device operating parameters (voltage,
frequency, temperature, etc.) must be
within their operating ranges; otherwise,
the device may not function correctly.
The user application must ensure that
the delay between the time power is first
applied, and the time SYSRST becomes
inactive, is long enough to get all operat-
ing parameters within specification.
The on-chip regulator has a Brown-out Reset (BOR)
circuit that resets the device when the VDD is too low
(VDD < VBOR) for proper device operation. The BOR
circuit keeps the device in Reset until VDD crosses the
VBOR threshold and the delay, TBOR, has elapsed. The
delay, TBOR, ensures the voltage regulator output
becomes stable.
The BOR status (BOR) bit in the Reset Control
(RCON<1>) register is set to indicate the Brown-out
Reset.
6.2
Power-on Reset (POR)
The device will not run at full speed after a BOR as the
VDD should rise to acceptable levels for full-speed
operation. The PWRT provides power-up time delay
(TPWRT) to ensure that the system power supplies have
stabilized at the appropriate levels for full-speed
operation before the SYSRST is released.
A Power-on Reset (POR) circuit ensures the device is
reset from power-on. The POR circuit is active until
VDD crosses the VPOR threshold and the delay, TPOR,
has elapsed. The delay, TPOR, ensures the internal
device bias circuits become stable.
The device supply voltage characteristics must meet
the specified starting voltage and rise rate
requirements to generate the POR. Refer to
Section 24.0 “Electrical Characteristics” for details.
The power-up timer delay (TPWRT) is programmed by
the
Power-on
Reset
Timer
Value
Select
(FPWRT<2:0>) bits in the POR Configuration
(FPOR<2:0>) register, which provides eight settings
(from 0 ms to 128 ms). Refer to Section 21.0 “Special
Features” for further details.
The POR status (POR) bit in the Reset Control
(RCON<0>) register is set to indicate the Power-on
Reset.
Figure 6-3 shows the typical brown-out scenarios. The
reset delay (TBOR + TPWRT) is initiated each time VDD
rises above the VBOR trip point

6.3
External Reset (EXTR)
The external Reset is generated by driving the MCLR
pin low. The MCLR pin is a Schmitt trigger input with an
additional glitch filter. Reset pulses that are longer than
the minimum pulse width will generate a Reset. Refer
to Section 24.0 “Electrical Characteristics” for
minimum pulse width specifications. The external
Reset (MCLR) pin (EXTR) bit in the Reset Control
(RCON) register is set to indicate the MCLR Reset.
The Software Reset (SWR) flag (instruction) in the
Reset Control (RCON<6>) register is set to indicate
the software Reset.
6.5
Watchdog Time-out Reset (WDTO)
Whenever a Watchdog time-out occurs, the device will
asynchronously assert SYSRST. The clock source will
remain unchanged. A WDT time-out during Sleep or
Idle mode will wake-up the processor, but will not reset
the processor.
6.3.0.1
EXTERNAL SUPERVISORY
CIRCUIT
Many systems have external supervisory circuits that
generate Reset signals to reset multiple devices in the
system. This external Reset signal can be directly
connected to the MCLR pin to reset the device when
the rest of system is reset.
The Watchdog Timer Time-out (WDTO) flag in the
Reset Control (RCON<4>) register is set to indicate
the Watchdog Reset. Refer to Section 21.4
“Watchdog Timer (WDT)” for more information on
Watchdog Reset.
6.3.0.2
INTERNAL SUPERVISORY CIRCUIT
When using the internal power supervisory circuit to
reset the device, the external Reset pin (MCLR) should
be tied directly or resistively to VDD. In this case, the
MCLR pin will not be used to generate a Reset. The
external Reset pin (MCLR) does not have an internal
pull-up and must not be left unconnected.
6.6
Trap Conflict Reset
If a lower priority hard trap occurs while a higher
priority trap is being processed, a hard Trap Conflict
Reset occurs. The hard traps include exceptions of pri-
ority level 13 through level 15, inclusive. The address
error (level 13) and oscillator error (level 14) traps fall
into this category.
6.4
Software RESETInstruction (SWR)
The Trap Reset (TRAPR) flag in the Reset Control
(RCON<15>) register is set to indicate the Trap Conflict
Reset. Refer to Section 7.0 “Interrupt Controller” for
more information on Trap Conflict Resets.
Whenever the RESET instruction is executed, the
device will assert SYSRST, placing the device in a
special Reset state. This Reset state will not
re-initialize the clock. The clock source in effect prior to

each program memory section to store the data values.
The upper 8 bits should be programmed with 3Fh,
which is an illegal opcode value.
6.7
Configuration Mismatch Reset
To maintain the integrity of the Peripheral Pin Select
Control registers, they are constantly monitored with
shadow registers in hardware. If an unexpected
change in any of the registers occur (such as cell
disturbances caused by ESD or other external events),
a Configuration Mismatch Reset occurs.
6.8.2
UNINITIALIZED W REGISTER
RESET
Any attempt to use the uninitialized W register as an
Address Pointer will Reset the device. The W register
array (with the exception of W15) is cleared during all
Resets and is considered uninitialized until written to.
The Configuration Mismatch (CM) flag in the Reset
Control (RCON<9>) register is set to indicate the
Configuration Mismatch Reset. Refer to Section 10.0
“I/O Ports” for more information on the
Configuration Mismatch Reset.
6.8.3
SECURITY RESET
If a Program Flow Change (PFC) or Vector Flow
Change (VFC) targets a restricted location in a
protected segment (boot and secure segment), that
operation will cause a Security Reset.
Note:
The Configuration Mismatch Reset
feature and associated Reset flag are not
available on all devices.
The PFC occurs when the program counter is reloaded
as a result of a call, jump, computed jump, return,
return from subroutine or other form of branch
instruction.
6.8
Illegal Condition Device Reset
An illegal condition device Reset occurs due to the
following sources:
The VFC occurs when the program counter is reloaded
with an interrupt or trap vector.
• Illegal Opcode Reset
• Uninitialized W Register Reset
• Security Reset
Refer to Section 21.8 “Code Protection and
CodeGuard™ Security” for more information on
Security Reset.
The Illegal Opcode or Uninitialized W Access Reset
(IOPUWR) flag in the Reset Control (RCON<14>)
register is set to indicate the illegal condition device
Reset.
6.9
Using the RCON Status Bits
The user application can read the Reset Control
(RCON) register after any device Reset to determine
the cause of the Reset.
6.8.1
ILLEGAL OPCODE RESET
A device Reset is generated if the device attempts to
execute an illegal opcode value that is fetched from
program memory.
Note: The status bits in the RCON register
should be cleared after they are read so
that the next RCON register value after a
device Reset will be meaningful.
The Illegal Opcode Reset function can prevent the
device from executing program memory sections that
are used to store constant data. To take advantage of
the Illegal Opcode Reset, use only the lower 16 bits of
Table 6-3 provides a summary of the Reset flag bit
operation.

(www.microchip.com).
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. If the AIVT is not
needed, the AIVT should be programmed with the
same addresses used in the IVT.
The dsPIC33FJ06GS101/X02 and dsPIC33FJ16GSX02/
X04 interrupt controller reduces the numerous peripheral
interrupt request signals to a single interrupt request
signal
to
the
dsPIC33FJ06GS101/X02
and
dsPIC33FJ16GSX02/X04 CPU. It has the following
features:
7.2
Reset Sequence
• Up to eight processor exceptions and software
traps
A device Reset is not a true exception because the
interrupt controller is not involved in the Reset process.
The dsPIC33FJ06GS101/X02 and dsPIC33FJ16GSX02/
X04 device clears its registers in response to a Reset,
which forces the PC to zero. The digital signal controller
then begins program execution at location 0x000000. A
GOTO instruction at the Reset address can redirect
program execution to the appropriate start-up routine.
• Seven user-selectable priority levels
• Interrupt Vector Table (IVT) with up to 118 vectors
• A unique vector for each interrupt or exception
source
• Fixed priority within a specified user priority level
• Alternate Interrupt Vector Table (AIVT) for debug
support
Note: Any unimplemented or unused vector
locations in the IVT and AIVT should be
programmed with the address of a default
interrupt handler routine that contains a
RESETinstruction.
• Fixed interrupt entry and return latencies
7.1
Interrupt Vector Table
The Interrupt Vector Table (IVT) is shown in Figure 7-1.
The IVT resides in program memory, starting at location
000004h. The IVT contains 126 vectors, consisting of
eight nonmaskable trap vectors, plus up to 118 sources
of interrupt. In general, each interrupt source has its own
vector. Each interrupt vector contains a 24-bit-wide
address. The value programmed into each interrupt
vector location is the starting address of the associated
Interrupt Service Routine (ISR).
Interrupt vectors are prioritized in terms of their natural
priority. This priority is linked to their position in the
vector table. Lower addresses generally have a higher
natural priority. For example, the interrupt associated
with vector 0 will take priority over interrupts at any
other vector address.
The dsPIC33FJ06GS101/X02 and dsPIC33FJ16GSX02/
X04 devices implement up to 35 unique interrupts and
4 non-maskable traps. These are summarized in
Table 7-1.

7.3.5
INTTREG
7.3
Interrupt Control and Status
Registers
The INTTREG register contains the associated
interrupt vector number and the new CPU Interrupt
priority Level, which are latched into the Vector Number
(VECNUM<6:0>) and Interrupt Level (ILR<3:0>) bit
fields in the INTTREG register. The new Interrupt
Priority Level is the priority of the pending interrupt.
The dsPIC33FJ06GS101/X02 and dsPIC33FJ16GSX02/
X04 devices implement 27 registers for the interrupt
controller:
• INTCON1
• INTCON2
• IFSx
• IECx
• IPCx
The interrupt sources are assigned to the IFSx, IECx
and IPCx registers in the same sequence that they are
listed in Table 7-1. For example, the INT0 (External
Interrupt 0) is shown as having vector number 8 and a
natural order priority of 0. Thus, the INT0IF bit is found
in IFS0<0>, the INT0IE bit is found in IEC0<0> and the
INT0IP bits are found in the first position of IPC0
(IPC0<2:0>).
• INTTREG
7.3.1
INTCON1 AND INTCON2
Global interrupt control functions are controlled from
INTCON1 and INTCON2. INTCON1 contains the
Interrupt Nesting Disable (NSTDIS) bit as well as the
control and status flags for the processor trap sources.
The INTCON2 register controls the external interrupt
request signal behavior and the use of the Alternate
Interrupt Vector Table.
7.3.6
STATUS/CONTROL REGISTERS
Although they are not specifically part of the interrupt
control hardware, two of the CPU Control registers
contain bits that control interrupt functionality.
• The CPU STATUS register, SR, contains the
IPL<2:0> bits (SR<7:5>). These bits indicate the
current CPU interrupt Priority Level. The user can
change the current CPU priority level by writing to
the IPL bits.
7.3.2
IFSx
The IFSx registers maintain all of the interrupt request
flags. Each source of interrupt has a status bit, which is
set by the respective peripherals or external signal and
is cleared via software.
• The CORCON register contains the IPL3 bit,
which together with IPL<2:0>, indicates the
current CPU priority level. IPL3 is a read-only bit
so that trap events cannot be masked by the user
software.
7.3.3
IECx
The IECx registers maintain all of the interrupt enable
bits. These control bits are used to individually enable
interrupts from the peripherals or external signals.
All Interrupt registers are described in Register 7-1
through Register 7-35 in the following pages.
7.3.4
IPCx
The IPCx registers are used to set the Interrupt Priority
Level for each source of interrupt. Each user interrupt
source can be assigned to one of eight priority levels.

TRAP SERVICE ROUTINE
7.4
Interrupt Setup Procedures
A Trap Service Routine (TSR) is coded like an ISR,
except that the appropriate trap status flag in the
INTCON1 register must be cleared to avoid re-entry
into the TSR.
7.4.1
INITIALIZATION
Complete the following steps to configure an interrupt
source at initialization:
1. Set the NSTDIS bit (INTCON1<15>) if nested
interrupts are not desired.
7.4.4
INTERRUPT DISABLE
The following steps outline the procedure to disable all
user interrupts:
2. Select the user-assigned priority level for the
interrupt source by writing the control bits in the
appropriate IPCx register. The priority level will
depend on the specific application and type of
interrupt source. If multiple priority levels are not
desired, the IPCx register control bits for all
enabled interrupt sources can be programmed
to the same non-zero value.
1. Push the current SR value onto the software
stack using the PUSHinstruction.
2. Force the CPU to priority level 7 by inclusive
ORing the value EOh with SRL.
To enable user interrupts, the POP instruction can be
used to restore the previous SR value.
Note: At a device Reset, the IPCx registers are
initialized such that all user interrupt
sources are assigned to priority level 4.
Note:
Only user interrupts with a priority level of
7 or lower can be disabled. Trap sources
(level 8-level 15) cannot be disabled.
3. Clear the interrupt flag status bit associated with
the peripheral in the associated IFSx register.
The DISI instruction provides a convenient way to
disable interrupts of priority levels 1-6 for a fixed period
of time. Level 7 interrupt sources are not disabled by
the DISI instruction.
4. Enable the interrupt source by setting the
interrupt enable control bit associated with the
source in the appropriate IECx register.
7.4.2
INTERRUPT SERVICE ROUTINE
The method used to declare an ISR and initialize the
IVT with the correct vector address depends on the
programming language (C or assembler) and the
language development toolsuite used to develop the
application.
In general, the user application must clear the interrupt
flag in the appropriate IFSx register for the source of
interrupt that the ISR handles. Otherwise, program will
re-enter the ISR immediately after exiting the routine. If
the ISR is coded in assembly language, it must be
terminated using a RETFIE instruction to unstack the
saved PC value, SRL value and old CPU priority level.

SYSTEM CLOCK SOURCES
The Fast RC (FRC) internal oscillator runs at a nominal
frequency of 7.37 MHz. User software can tune the
FRC frequency. User software can optionally specify a
factor (ranging from 1:2 to 1:256) by which the FRC
clock frequency is divided. This factor is selected using
the FRCDIV<2:0> (CLKDIV<10:8>) bits.

The primary oscillator can use one of the following as
its clock source:
The Configuration bits allow users to choose among
12 different clock modes, shown in Table 8-1.
• XT (Crystal): Crystals and ceramic resonators in
the range of 3 MHz to 10 MHz. The crystal is
connected to the OSC1 and OSC2 pins.
The output of the oscillator (or the output of the PLL if
a PLL mode has been selected), FOSC, is divided by 2
to generate the device instruction clock (FCY) and the
peripheral clock time base (FP). FCY defines the
operating speed of the device and speeds up to 40
MHz are supported by the dsPIC33FJ06GS101/X02
and dsPIC33FJ16GSX02/X04 architecture.
• HS (High-Speed Crystal): Crystals in the range of
10 MHz to 40 MHz. The crystal is connected to
the OSC1 and OSC2 pins.
• EC (External Clock): The external clock signal is
directly applied to the OSC1 pin.
The LPRC internal oscIllator runs at a nominal
frequency of 32.768 kHz. It is also used as a reference
clock by the Watchdog Timer (WDT) and Fail-Safe
Clock Monitor (FSCM).
Instruction execution speed or device operating

For a primary oscillator or FRC oscillator, output ‘FIN’,
the PLL output ‘FOSC’ is given by Equation 8-2.
8.1.3
PLL CONFIGURATION
The primary oscillator and internal FRC oscillator can
optionally use an on-chip PLL to obtain higher speeds
of operation. The PLL provides significant flexibility in
selecting the device operating speed. A block diagram
of the PLL is shown in Figure 8-2.
EQUATION 8-2:
FOSC CALCULATION

N1*N2
FOSC = FIN *
(
)
The output of the primary oscillator or FRC, denoted as
‘FIN’, is divided down by a prescale factor (N1) of 2, 3,
... or 33 before being provided to the PLL’s Voltage
Controlled Oscillator (VCO). The input to the VCO must
be selected in the range of 0.8 MHz to 8 MHz. The
prescale factor ‘N1’ is selected using the
PLLPRE<4:0> bits (CLKDIV<4:0>).
For example, suppose a 10 MHz crystal is being used
with the selected oscillator mode of XT with PLL (see
Equation 8-3).
• If PLLPRE<4:0> = 0, then N1 = 2. This yields a
VCO input of 10/2 = 5 MHz, which is within the
acceptable range of 0.8-8 MHz.
• If PLLDIV<8:0> = 0x1E, then M = 32. This yields a
VCO output of 5 x 32 = 160 MHz, which is within
the 100-200 MHz ranged needed.
The PLL Feedback Divisor, selected using the
PLLDIV<8:0> bits (PLLFBD<8:0>), provides a factor, ‘M’,
by which the input to the VCO is multiplied. This factor
must be selected such that the resulting VCO output
frequency is in the range of 100 MHz to 200 MHz.
• If PLLPOST<1:0> = 0, then N2 = 2. This provides
a Fosc of 160/2 = 80 MHz. The resultant device
operating speed is 80/2 = 40 MIPS.
The VCO output is further divided by a postscale factor,
‘N2’. This factor is selected using the PLLPOST<1:0>
bits (CLKDIV<7:6>). ‘N2’ can be either 2, 4, or 8, and
must be selected such that the PLL output frequency
(FOSC) is in the range of 12.5 MHz to 80 MHz, which
generates device operating speeds of 6.25-40 MIPS.

Auxiliary Clock Generation
Note:
If the primary PLL is used as a source for
the auxiliary clock, then the primary PLL
should be configured up to a maximum
operation of 30 MIPS or less.
The auxiliary clock generation is used for a peripherals
that need to operate at a frequency unrelated to the
system clock such as a PWM or ADC.
Note:
To achieve 1.04 ns PWM resolution, the
auxiliary clock must be set up for 120 MHz.
8.3
Reference Clock Generation
The reference clock output logic provides the user with
the ability to output a clock signal based on the system
clock or the crystal oscillator on a device pin. The user
application can specify a wide range of clock scaling
prior to outputting the reference clock.
The primary oscillator and internal FRC oscillator
sources can be used with an auxiliary PLL to obtain the
auxiliary clock. The auxiliary PLL has a fixed 16x
multiplication factor.

Applications are free to switch among any of the four
clock sources (primary, LP, FRC and LPRC) under
software control at any time. To limit the possible side
effects of this flexibility, dsPIC33FJ06GS101/X02 and
dsPIC33FJ16GSX02/X04 devices have a safeguard
lock built into the switch process.
(OSCCON<3>) status bits are cleared.
3. The new oscillator is turned on by the hardware
if it is not currently running. If a crystal oscillator
must be turned on, the hardware waits until the
Oscillator Start-up Timer (OST) expires. If the
new source is using the PLL, the hardware waits
until a PLL lock is detected (LOCK = 1).
Note:
Primary oscillator mode has three different
submodes (XT, HS and EC), which are
determined by the POSCMD<1:0>
Configuration bits. While an application
can switch to and from primary oscillator
mode in software, it cannot switch among
the different primary submodes without
reprogramming the device.
4. The hardware waits for 10 clock cycles from the
new clock source and then performs the clock
switch.
5. The hardware clears the OSWEN bit to indicate a
successful clock transition. In addition, the NOSC
bit values are transferred to the COSC status bits.
6. The old clock source is turned off at this time,
with the exception of LPRC (if WDT or FSCM
are enabled).
8.4.1
ENABLING CLOCK SWITCHING
To enable clock switching, the FCKSM1 Configuration
bit in the Configuration register must be programmed to
‘0’. (Refer to Section 21.1 “Configuration Bits” for
further details.) If the FCKSM1 Configuration bit is
unprogrammed (‘1’), the clock switching function and
Fail-Safe Clock Monitor function are disabled. This is
the default setting.
Note 1: The processor continues to execute code
throughout the clock switching sequence.
Timing-sensitive code should not be
executed during this time.
2: Direct clock switches between any primary
oscillator mode with PLL and FRCPLL
mode are not permitted. This applies to
clock switches in either direction. In these
instances, the application must switch to
FRC mode as a transition clock source
between the two PLL modes.
3: Refer to Section 42. “Oscillator (Part
IV)” (DS70307) in the “dsPIC33F Family
Reference Manual” for details.
The NOSC control bits (OSCCON<10:8>) do not
control the clock selection when clock switching is
disabled. However, the COSC bits (OSCCON<14:12>)
reflect the clock source selected by the FNOSC
Configuration bits.
The OSWEN control bit (OSCCON<0>) has no effect
when clock switching is disabled. It is held at ‘0’ at all
times.
8.5
Fail-Safe Clock Monitor (FSCM)
8.4.2
OSCILLATOR SWITCHING SEQUENCE
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 programming.
If the FSCM function is enabled, the LPRC internal
oscillator runs at all times (except during Sleep mode)
and is not subject to control by the Watchdog Timer.
To perform a clock switch, the following basic sequence
is required:
1. If
desired,
read
the
COSC
bits
(OSCCON<14:12>) to determine the current
oscillator source.
2. Perform the unlock sequence to allow a write to
the OSCCON register high byte.
In the event of an oscillator failure, the FSCM
generates a clock failure trap event and switches the
system clock over to the FRC oscillator. Then, the
application program can either attempt to restart the
oscillator or execute a controlled shutdown. The trap
can be treated as a warm Reset by simply loading the
Reset address into the oscillator fail trap vector.
3. Write the appropriate value to the NOSC control
bits (OSCCON<10:8>) for the new oscillator
source.
4. Perform the unlock sequence to allow a write to
the OSCCON register low byte.
5. Set the OSWEN bit (OSCCON<0>) to initiate the
oscillator switch.
If the PLL multiplier is used to scale the system clock,
the internal FRC is also multiplied by the same factor
on clock failure. Essentially, the device switches to
FRC with PLL on a clock failure.
Once the basic sequence is completed, the system
clock hardware responds automatically as follows:
1. The clock switching hardware compares the
COSC status bits with the new value of the
NOSC control bits. If they are the same, the
clock switch is a redundant operation. In this
case, the OSWEN bit is cleared automatically
and the clock switch is aborted.

This data sheet summarizes the features
of the dsPIC33FJ06GS101/X02 and

devices. It is not intended to be a

complement the information in this data
sheet, refer to the “dsPIC33F Family
The dsPIC33FJ06GS101/X02 and dsPIC33FJ16GSX02/
X04 devices have two special power-saving modes that
are entered through the execution of a special PWRSAV
instruction. Sleep mode stops clock operation and halts all
code execution. Idle mode halts the CPU and code
execution, but allows peripheral modules to continue
operation. The assembler syntax of the PWRSAV
instruction is shown in Example 9-1.

Modes” (DS70196), which is available
from the Microchip web site (www.micro-
chip.com).
Note: SLEEP_MODE and IDLE_MODE are
constants defined in the assembler
include file for the selected device.
The dsPIC33FJ06GS101/X02 and dsPIC33FJ16GSX02/
X04 devices provide the ability to manage power
consumption by selectively managing clocking to the
CPU and the peripherals. In general, a lower clock
frequency and a reduction in the number of circuits being
Sleep and Idle modes can be exited as a result of an
enabled interrupt, WDT time-out or a device Reset. When
the device exits these modes, it is said to wake-up.
9.2.1
SLEEP MODE
clocked
constitutes
lower
consumed
power.
The following occur in Sleep mode:
dsPIC33FJ06GS101/X02 and dsPIC33FJ16GSX02/X04
devices can manage power consumption in four different
ways:
• The system clock source is shut down. If an
on-chip oscillator is used, it is turned off.
• The device current consumption is reduced to a
minimum, provided that no I/O pin is sourcing
current.
• Clock Frequency
• Instruction-Based Sleep and Idle modes
• Software-Controlled Doze mode
• Selective Peripheral Control in Software
• The Fail-Safe Clock Monitor does not operate,
since the system clock source is disabled.
Combinations of these methods can be used to
selectively tailor an application’s power consumption
while still maintaining critical application features, such
as timing-sensitive communications.
• The LPRC clock continues to run in Sleep mode if
the WDT is enabled.
• The WDT, if enabled, is automatically cleared
prior to entering Sleep mode.
• Some device features or peripherals may continue
to operate. This includes the items such as the
input change notification on the I/O ports or
peripherals that use an external clock input.
9.1
Clock Frequency and Clock
Switching
The
dsPIC33FJ06GS101/X02
and
dsPIC33FJ16GSX02/X04 devices allow a wide range
of clock frequencies to be selected under application
control. If the system clock configuration is not locked,
users can choose low-power or high-precision
oscillators by simply changing the NOSC bits
(OSCCON<10:8>). The process of changing a system
clock during operation, as well as limitations to the
process, are discussed in more detail in Section 8.0
“Oscillator Configuration”.
• Any peripheral that requires the system clock
source for its operation is disabled.
The device will wake-up from Sleep mode on any of
these events:
• Any interrupt source that is individually enabled
• Any form of device Reset
• A WDT time-out
On wake-up from Sleep mode, the processor restarts
with the same clock source that was active when Sleep
mode was entered.

Doze mode is enabled by setting the DOZEN bit
(CLKDIV<11>). The ratio between peripheral and core
clock speed is determined by the DOZE<2:0> bits
(CLKDIV<14:12>). There are eight possible
configurations, from 1:1 to 1:128, with 1:1 being the
default setting.
9.2.2
IDLE MODE
The following occur in Idle mode:
• The CPU stops executing instructions.
• The WDT is automatically cleared.
• The system clock source remains active. By
default, all peripheral modules continue to operate
normally from the system clock source, but can
also be selectively disabled (see Section 9.4
“Peripheral Module Disable”).
Programs can use Doze mode to selectively reduce
power consumption in event-driven applications. This
allows clock-sensitive functions, such as synchronous
communications, to continue without interruption while
the CPU idles, waiting for something to invoke an
interrupt routine. An automatic return to full-speed CPU
operation on interrupts can be enabled by setting the
ROI bit (CLKDIV<15>). By default, interrupt events
have no effect on Doze mode operation.
• If the WDT or FSCM is enabled, the LPRC also
remains active.
The device will wake-up from Idle mode on any of these
events:
• Any interrupt that is individually enabled
• Any device Reset
• A WDT time-out
For example, suppose the device is operating at
20 MIPS and the CAN module has been configured for
500 kbps based on this device operating speed. If the
device is placed in Doze mode with a clock frequency
ratio of 1:4, the CAN module continues to communicate
at the required bit rate of 500 kbps, but the CPU now
starts executing instructions at a frequency of 5 MIPS.
On wake-up from Idle mode, the clock is reapplied to
the CPU and instruction execution begins immediately,
starting with the instruction following the PWRSAV
instruction, or the first instruction in the ISR.
9.2.3
INTERRUPTS COINCIDENT WITH
POWER SAVE INSTRUCTIONS
9.4
Peripheral Module Disable
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 using the appropriate
PMD control bit, the peripheral is in a minimum power
consumption state. The control and status registers
associated with the peripheral are also disabled, so
writes to those registers will have no effect and read
values will be invalid.
Any interrupt that coincides with the execution of a
PWRSAVinstruction is held off until entry into Sleep or
Idle mode has completed. The device then wakes up
from Sleep or Idle mode.
9.3
Doze Mode
The preferred strategies for reducing power
consumption are changing clock speed and invoking
one of the power-saving modes. In some
circumstances, this may not be practical. For example,
it may be necessary for an application to maintain
uninterrupted synchronous communication, even while
it is doing nothing else. Reducing system clock speed
can introduce communication errors, while using a
power-saving mode can stop communications
completely.
A peripheral module is enabled only 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.
Note:
If a PMD bit is set, the corresponding
module is disabled after a delay of one
instruction cycle. Similarly, if a PMD bit is
cleared, the corresponding module is
enabled after a delay of one instruction
cycle (assuming the module control regis-
ters are already configured to enable
module operation).
Doze mode is a simple and effective alternative method
to reduce power consumption while the device is still
executing code. In this mode, the system clock
continues to operate from the same source and at the
same speed. Peripheral modules continue to be
clocked at the same speed, while the CPU clock speed
is reduced. Synchronization between the two clock
domains is maintained, allowing the peripherals to
access the SFRs while the CPU executes code at a
slower rate.

of the dsPIC33FJ06GS101/X02 and
dsPIC33FJ16GSX02/X04 families of
devices. It is not intended to be a
comprehensive reference source. To
complement the information in this data
sheet, refer to the “dsPIC33F Family
Reference Manual”, Section 10. “I/O
Ports” (DS70193), which is available on
Microchip web site (www.microchip.com).
associated I/O pin to which they are connected.
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.
All port pins have three registers directly associated
with their operation as digital I/O. The data direction
register (TRISx) determines whether the pin is an input
or an output. If the data direction bit is ‘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.
Writes to the latch write the latch. Reads from the port
(PORTx) read the port pins, while writes to the port pins
write the latch.
All of the device pins (except VDD, VSS, MCLR and
OSC1/CLKI) are shared among the peripherals and the
parallel I/O ports. All I/O input ports feature Schmitt
Trigger inputs for improved noise immunity.
10.1 Parallel I/O (PIO) Ports
Generally a parallel I/O port that shares a pin with a
peripheral is 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 pin. The logic also prevents “loop through”, in
which a port’s digital output can drive the input of a
Any bit and its associated data and control registers
that are not valid for a particular device will be
disabled. That means the corresponding LATx and
TRISx registers and the port pin will 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.

OPEN-DRAIN CONFIGURATION
10.2.1
I/O PORT WRITE/READ TIMING
In addition to the PORT, LAT and TRIS registers for
data control, some digital-only port pins can also be
individually configured for either digital or open-drain
output. This is controlled by the Open-Drain Control
register, ODCx, associated with each port. Setting any
of the bits configures the corresponding pin to act as an
open-drain output.
Oneinstructioncycleisrequiredbetweenaportdirection
change or port write operation and a read operation of
the same port. Typically, this instruction would be a NOP.
An example is shown in Example 10-1.
10.3 Input Change Notification
The input change notification function of the I/O
ports allows the dsPIC33FJ06GS101/X02 and
dsPIC33FJ16GSX02/X04 devices to generate interrupt
The open-drain feature allows the generation of
outputs higher than VDD (for example, 5V) on any
desired digital only pins by using external pull-up
resistors. The maximum open-drain voltage allowed is
the same as the maximum VIH specification.
requests to the processor in response to
a
Change-Of-State (COS) on selected input pins. This
feature can detect input Change-Of-States even in
Sleep mode, when the clocks are disabled. Depending
on the device pin count, up to 30 external signals (CNx
pin) can be selected (enabled) for generating an
interrupt request on a Change-Of-State.
Refer to “Pin Diagrams” for the available pins and
their functionality.
10.2 Configuring Analog Port Pins
Four control registers are associated with the CN
module. The CNEN1 and CNEN2 registers contain the
interrupt enable control bits for each of the CN input
pins. Setting any of these bits enables a CN interrupt
for the corresponding pins.
The ADPCFG and TRIS registers control the operation
of the Analog-to-Digital (A/D) port pins. The port pins
that are to function 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.
Each CN pin also has a weak pull-up connected to it.
The pull-ups act as a current source connected to the
pin, and eliminate the need for external resistors when
the push button or keypad devices are connected. The
pull-ups are enabled separately using the CNPU1 and
CNPU2 registers, which contain the control bits for
each of the CN pins. Setting any of the control bits
enables the weak pull-ups for the corresponding pins.
The ADPCFG register has a default value of 0x0000;
therefore, all pins that share ANx functions are analog
(not digital) by default.
When the PORT register is read, all pins configured as
analog input channels will read as cleared (a low level).
Pins configured as digital inputs will not convert an
analog input. Analog levels on any pin defined as a
digital input (including the ANx pins) can cause the
input buffer to consume current that exceeds the
device specifications.
Note:
Pull-ups on change notification pins
should always be disabled when the port
pin is configured as a digital output.

Input Mapping
10.4 Peripheral Pin Select
The inputs of the peripheral pin select options are
mapped on the basis of the peripheral. A control
register associated with a peripheral dictates the pin it
will be mapped to. The RPINRx registers are used to
configure peripheral input mapping (see Register 10-1
through Register 10-14). Each register contains sets of
6-bit fields, with each set associated with one of the
Peripheral pin select configuration enables peripheral
set selection and placement on a wide range of I/O
pins. By increasing the pinout options available on a
particular device, programmers can better tailor the
microcontroller to their entire application, rather than
trimming the application to fit the device.
The peripheral pin select configuration feature operates
over a fixed subset of digital I/O pins. Programmers can
independently map the input and/or output of most
digital peripherals to any one of these I/O pins.
Peripheral pin select is performed in software, and gen-
erally does not require the device to be reprogrammed.
Hardware safeguards are included that prevent acciden-
tal or spurious changes to the peripheral mapping, once
it has been established.
remappable peripherals. Programming
a
given
peripheral’s bit field with an appropriate 6-bit value
maps the RPn pin with that value to that peripheral. For
any given device, the valid range of values for any bit
field corresponds to the maximum number of peripheral
pin selections supported by the device.
Figure 10-2 Illustrates remappable pin selection for
U1RX input.
Note:
For input mapping only, the Peripheral Pin
Select (PPS) functionality does not have
priority over the TRISx settings. Therefore,
when configuring the RPx pin for input, the
corresponding bit in the TRISx register
must also be configured for input (i.e., set
to ‘1’).
10.4.1
AVAILABLE PINS
The peripheral pin select feature is used with a range
of up to 30 pins. The number of available pins depends
on the particular device and its pin count. Pins that
support the peripheral pin select feature include the
designation “RPn” in their full pin designation, where
“RP” designates a remappable peripheral and “n” is the
remappable pin number.

Output Mapping
FIGURE 10-3:
MULTIPLEXING OF
REMAPPABLE OUTPUT
FOR RPn
In contrast to inputs, the outputs of the peripheral pin
select options are mapped on the basis of the pin. In
this case, a control register associated with a particular
pin dictates the peripheral output to be mapped. The
RPORx registers are used to control output mapping.
Like the RPINRx registers, each register contains sets
of 6-bit fields, with each set associated with one RPn
pin (see Register 10-15 through Register 10-31). The
value of the bit field corresponds to one of the
peripherals, and that peripheral’s output is mapped to
the pin (see Table 10-2 and Figure 10-3).

dsPIC33FJ06GS101/X02 and dsPIC33FJ16GSX02/X04
Unlike the similar sequence with the oscillator’s LOCK
bit, IOLOCK remains in one state until changed. This
allows all of the peripheral pin selects to be configured
with a single unlock sequence followed by an update to
all control registers, then locked with a second lock
sequence.
10.4.2.3
Virtual Pins
dsPIC33FJ06GS101/X02
and
dsPIC33FJ16GSX02/X04 devices support four virtual
RPn pins (RP32, RP33, RP34 and RP35), which are
identical in functionality to all other RPn pins, with the
exception of pinouts. These four pins are internal to the
devices and are not connected to a physical device pin.
10.4.3.2
Continuous State Monitoring
These pins provide a simple way for inter-peripheral
connection without utilizing a physical pin. For example,
the output of the analog comparator can be connected to
RP32 and the PWM Fault input can be configured for
RP32 as well. This configuration allows the analog
comparator to trigger PWM Faults without the use of an
actual physical pin on the device.
In addition to being protected from direct writes, the
contents of the RPINRx and RPORx registers are
constantly monitored in hardware by shadow registers.
If an unexpected change in any of the registers occurs
(such as cell disturbances caused by ESD or other
external events), a Configuration Mismatch Reset will
be triggered.
10.4.3
CONTROLLING CONFIGURATION
CHANGES
10.4.3.3
Configuration Bit Pin Select Lock
As an additional level of safety, the device can be
configured to prevent more than one write session to
the RPINRx and RPORx registers. The IOL1WAY
(FOSC<5>) Configuration bit blocks the IOLOCK bit
from being cleared after it has been set once. If
IOLOCK remains set, the register unlock procedure will
not execute and the Peripheral Pin Select Control
registers cannot be written to. The only way to clear the
bit and re-enable peripheral remapping is to perform a
device Reset.
Because peripheral remapping can be changed during
run time, some restrictions on peripheral remapping
are needed to prevent accidental configuration
changes. dsPIC33F devices include three features to
prevent alterations to the peripheral map:
• Control register lock sequence
• Continuous state monitoring
• Configuration bit pin select lock
10.4.3.1
Control Register Lock
In the default (unprogrammed) state, IOL1WAY is set,
restricting users to one write session. Programming
IOL1WAY allows user applications unlimited access
(with the proper use of the unlock sequence) to the
Peripheral Pin Select registers.
Under normal operation, writes to the RPINRx and
RPORx registers are not allowed. Attempted writes
appear to execute normally, but the contents of the
registers remain unchanged. To change these
registers, they must be unlocked in hardware. The
register lock is controlled by the IOLOCK bit
(OSCCON<6>). Setting IOLOCK prevents writes to the
control registers; clearing IOLOCK allows writes.
To set or clear IOLOCK, a specific command sequence
must be executed:
1. Write 0x46 to OSCCON<7:0>.
2. Write 0x57 to OSCCON<7:0>.
3. Clear (or set) IOLOCK as a single operation.
Note:
MPLAB® C30 provides built-in C language
functions for unlocking the OSCCON
register:
__builtin_write_OSCCONL(value)
__builtin_write_OSCCONH(value)
See MPLAB C30 Help files for more
information.

The Timer1 module can operate in one of the following
modes:
11.0 TIMER1
Note:
This data sheet summarizes the features of
• Timer mode
• Gated Timer mode
• Synchronous Counter mode
• Asynchronous Counter mode
the
dsPIC33FJ06GS101/X02
families
and
of
dsPIC33FJ16GSX02/X04
devices. It is not intended to be a
comprehensive reference source. To
complement the information in this data
sheet, refer to the “dsPIC33F Family
Reference Manual”, Section 11. “Timers”
(DS70205), which is available from the
Microchip web site (www.microchip.com).
In Timer and Gated Timer modes, the input clock is
derived from the internal instruction cycle clock (FCY).
In Synchronous and Asynchronous Counter modes,
the input clock is derived from the external clock input
at the T1CK pin.
The Timer modes are determined by the following bits:
• Timer Clock Source Control bit (TCS): T1CON<1>
The Timer1 module is a 16-bit timer, which can serve
as a time counter for the Real-Time Clock (RTC), or
operate as a free-running interval timer/counter.
• Timer Synchronization Control bit (TSYNC):
T1CON<2>
The Timer1 module has the following unique features
over other timers:
• Timer Gate Control bit (TGATE): T1CON<6>
The timer control bit settings for different operating
modes are given in the Table 11-1.
• Can be operated from the low-power 32 kHz
crystal oscillator available on the device
• Can be operated in Asynchronous Counter mode
from an external clock source.
TABLE 11-1: TIMER MODE SETTINGS
• The external clock input (T1CK) can optionally be
synchronized to the internal device clock and the
clock synchronization is performed after the
prescaler.

The Timer2/3 module can operate in one of the
following modes:
When configured for 32-bit operation, only the Type B
Timer Control (TxCON) register bits are required for
setup and control while the Type C Timer Control
register bits are ignored (except the TSIDL bit).
• Timer mode
• Gated Timer mode
• Synchronous Counter mode
For interrupt control, the combined 32-bit timer uses
the interrupt enable, interrupt flag and interrupt priority
control bits of the Type C timer. The interrupt control
and status bits for the Type B timer are ignored
during 32-bit timer operation.
In Timer and Gated Timer modes, the input clock is
derived from the internal instruction cycle clock (FCY).
In Synchronous Counter mode, the input clock is
derived from the external clock input at the TxCK pin.
The Timer2 and Timer 3 that can be combined to form a
32-bit timer are listed in Table 12-2.
The timer modes are determined by the following bits:
• TCS (TxCON<1>): Timer Clock Source Control bit
• TGATE (TxCON<6>): Timer Gate Control bit
TABLE 12-2: 32-BIT TIMER
Timer control bit settings for different operating modes
are given in the Table 12-1.

To configure the features of Timer2/3 for 32-bit
operation:
12.1 16-Bit Operation
1. Set the T32 control bit.
To configure any of the timers for individual 16-bit
operation:
2. Select the prescaler ratio for Timer2 using the
TCKPS<1:0> bits.
1. Clear the T32 bit corresponding to that timer.
3. Set the Clock and Gating modes using the
corresponding TCS and TGATE bits.
2. Select the timer prescaler ratio using the
TCKPS<1:0> bits.
4. Load the timer period value. PR3 contains the
most significant word of the value, while PR2
contains the least significant word.
3. Set the Clock and Gating modes using the TCS
and TGATE bits.
4. Load the timer period value into the PRx
register.
5. If interrupts are required, set the interrupt enable
bit, T3IE. Use the priority bits, T3IP<2:0>, to set
the interrupt priority. While Timer2 controls the
timer, the interrupt appears as a Timer3
interrupt.
5. If interrupts are required, set the interrupt enable
bit, TxIE. Use the priority bits, TxIP<2:0>, to set
the interrupt priority.
6. Set the TON bit.
6. Set the corresponding TON bit.
The timer value at any point is stored in the register
pair, TMR3:TMR2, which always contains the most
significant word of the count, while TMR2 contains the
least significant word.
12.2 32-Bit Operation
A 32-bit timer module can be formed by combining a
Type B and a Type C 16-bit timer module. For 32-bit
timer operation, the T32 control bit in the Type B Timer
Control (TxCON<3>) register must be set. The Type C
timer holds the most significant word (msw) and the
Type B timer holds the least significant word (lsw)
for 32-bit operation.

- Capture timer value on every rising edge of
input at ICx pin
• Capture timer value on every edge (rising and
falling)
• Prescaler Capture Event modes:
- Capture timer value on every 4th rising edge
of input at ICx pin
on
the
Microchip
web
site
- Capture timer value on every 16th rising
edge of input at ICx pin
(www.microchip.com).
Each input capture channel can select one of the
two 16-bit timers (Timer2 or Timer3) for the time
base. The selected timer can use either an internal
or external clock.
The input capture module is useful in applications
requiring frequency (period) and pulse measurement.
The
dsPIC33FJ06GS101/X02
and
dsPIC33FJ16GSX02/X04 devices support up to two
input capture channels.
Other operational features include:
The input capture module captures the 16-bit value of
the selected Time Base register when an event occurs
at the ICx pin. The events that cause a capture event
are listed below in three categories:
• Device wake-up from capture pin during CPU
Sleep and Idle modes
• Interrupt on input capture event
• 4-word FIFO buffer for capture values
- Interrupt optionally generated after 1, 2, 3 or
4 buffer locations are filled
• Use of input capture to provide additional sources
of external interrupts

PWM
module
on
the
dsPIC33FJ06GS101/X02 and dsPIC33FJ16GSX02/
X04 devices supports a wide variety of PWM modes
and output formats. This PWM module is ideal for
power conversion applications, such as:
The PWM module contains four PWM generators. The
module has up to eight PWM output pins: PWM1H,
PWM1L, PWM2H, PWM2L, PWM3H, PWM3L,
PWM4H and PWM4L. For complementary outputs,
these eight I/O pins are grouped into H/L pairs.
• AC/DC Converters
• DC/DC Converters
• Power Factor Correction(PFC)
• Uninterruptible Power Supply (UPS)
• Inverters
• Battery Chargers
• Digital Lighting
15.2 Feature Description
The PWM module is designed for applications that
require:
15.1 Features Overview
The high-speed PWM module incorporates the
following features:
• High-resolution at high PWM frequencies
• The ability to drive Standard, Edge-Aligned,
Center-Aligned Complementary mode, and
Push-Pull mode outputs
• 2-4 PWM generators with 4-8 outputs
• Individual time base and duty cycle for each of the
eight PWM outputs
• The ability to create multiphase PWM outputs
• Dead time for rising and falling edges:
• Duty cycle resolution of 1.04 ns at 40 MIPS
• Dead-time resolution of 1.04 ns at 40 MIPS
• Phase shift resolution of 1.04 ns at 40 MIPS
• Frequency resolution of 1.04 ns at 40 MIPS
• PWM modes supported:
- Standard Edge-Aligned
- True Independent Output
- Complementary
For Center-Aligned mode, the duty cycle, period phase
and dead-time resolutions will be 8 ns.
Two common, medium power converter topologies are
push-pull and half-bridge. These designs require the
PWM output signal to be switched between alternate
pins, as provided by the Push-Pull PWM mode.
Phase-shifted PWM describes the situation where
each PWM generator provides outputs, but the phase
relationship between the generator outputs is
specifiable and changeable.
- Center-Aligned
Multiphase PWM is often used to improve DC/DC
converter load transient response, and reduce the size
of output filter capacitors and inductors. Multiple DC/DC
converters are often operated in parallel, but
phase-shifted in time. A single PWM output operating at
250 kHz has a period of 4 μs, but an array of four PWM
channels, staggered by 1 μs each, yields an effective
switching frequency of 1 MHz. Multiphase PWM
applications typically use a fixed-phase relationship.
- Push-Pull
- Multiphase
- Variable Phase
- Fixed Off-Time
- Current Reset
- Current-Limit
• Independent Fault/Current-Limit inputs for each of
the eight PWM outputs
Variable phase PWM is useful in Zero Voltage
Transition (ZVT) power converters. Here, the PWM
duty cycle is always 50%, and the power flow is
controlled by varying the relative phase shift between
the two PWM generators.
• Output override control
• Special Event Trigger
• PWM capture feature
• Prescaler for input clock

dsPIC33FJ06GS101/X02 and dsPIC33FJ16GSX02/X04
The SPI module consists of a 16-bit shift register,
16.0 SERIAL PERIPHERAL
SPIxSR (where x = 1), used for shifting data in and out,
and a buffer register, SPIxBUF. A control register,
SPIxCON, configures the module. Additionally, a status
register, SPIxSTAT, indicates status conditions.
INTERFACE (SPI)
Note:
This data sheet summarizes the features
of the dsPIC33FJ06GS101/X02 and
dsPIC33FJ16GSX02/X04 families of
devices. It is not intended to be a
comprehensive reference source. To
complement the information in this data
sheet, refer to the “dsPIC33F Family
Reference Manual”, Section 18. “Serial
Peripheral Interface (SPI)” (DS70206),
which is available on the Microchip
web site (www.microchip.com).
The serial interface consists of the following four pins:
• SDIx (Serial Data Input)
• SDOx (Serial Data Output)
• SCKx (Shift Clock Input Or Output)
• SSx (Active-Low Slave Select).
In Master mode operation, SCK is a clock output; in
Slave mode, it is a clock input.
The Serial Peripheral Interface (SPI) module is a
synchronous serial interface useful for communicating
with other peripheral or microcontroller devices. These
peripheral devices can be serial EEPROMs, shift
registers, display drivers, analog-to-digital converters
and so on. The SPI module is compatible with SPI and
SIOP from Motorola®.

I2CxCON and I2CxSTAT are control and status
registers, respectively. The I2CxCON register is
readable and writable. The lower six bits of I2CxSTAT
are read-only. The remaining bits of the I2CSTAT are
read/write:

• I2CxRCV is the receive buffer and the register to
which data bytes are written, or from which data
bytes are read.
Circuit
(I2C™)”
• I2CxTRN is the transmit register to which bytes
are written during a transmit operation.
The Inter-Integrated Circuit (I2C) module provides
complete hardware support for both Slave and
Multi-Master modes of the I2C serial communication
standard with a 16-bit interface.
• The I2CxADD register holds the slave address.
• A status bit, ADD10, indicates 10-Bit Address
mode.
The I2C module has a 2-pin interface:
• The I2CxBRG acts as the Baud Rate Generator
(BRG) reload value.
• The SCLx pin is clock.
• The SDAx pin is data.
The I2C module offers the following key features:
• I2C interface supporting both Master and Slave
modes of operation.
In receive operations, I2CxRSR and I2CxRCV together
form a double-buffered receiver. When I2CxRSR
receives a complete byte, it is transferred to I2CxRCV,
and an interrupt pulse is generated.
• 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).
• I2C supports multi-master operation, detects bus
collision and arbitrates accordingly.
17.1 Operating Modes
The hardware fully implements all the master and slave
functions of the I2C Standard and Fast mode
specifications, as well as 7-bit and 10-bit addressing.
The I2C module can operate either as a slave or a
master on an I2C bus.
The following types of I2C operation are supported:
• I2C slave operation with 7-bit addressing
• I2C slave operation with 10-bit addressing
• I2C master operation with 7-bit or 10-bit addressing
For details about the communication sequence in each
of these modes, refer to the “dsPIC33F Family
Reference Manual”. Please see the Microchip web site
(www.microchip.com) for the latest “dsPIC33F Family
Reference Manual” chapters.

19.2 Module Description
19.0 HIGH-SPEED 10-BIT
ANALOG-TO-DIGITAL
CONVERTER (ADC)
This ADC module is designed for applications that
require low latency between the request for conversion
and the resultant output data. Typical applications
include:
Note:
This data sheet summarizes the features
of the dsPIC33FJ06GS101/X02 and

sheet, refer to the “dsPIC33F Family
• AC/DC power supplies
• DC/DC converters
• Power Factor Correction (PFC)
This ADC works with the high-speed PWM module in
power control applications that require high-frequency
control loops. This module can sample and convert two
analog inputs in a 0.5 microsecond when two SARs are
used. This small conversion delay reduces the “phase
lag” between measurement and control system
response.
Reference
Manual”,
Section
44.
“High-Speed 10-Bit Analog-to-Digital
Converter (ADC)” (DS70321), which is
available on the Microchip web site
(www.microchip.com).
Up to five inputs may be sampled at a time (four inputs
from the dedicated sample and hold circuits and one
from the shared sample and hold circuit). If multiple
inputs request conversion, the ADC will convert them in
a sequential manner, starting with the lowest order
input.
The
dsPIC33FJ06GS101/X02
and
dsPIC33FJ16GSX02/X04 devices provide high-speed
successive approximation analog to digital conversions to
support applications such as AC/DC and DC/DC power
converters.
This ADC design provides each pair of analog inputs
(AN1,AN0), (AN3,AN2),..., the ability to specify its own
trigger source out of a maximum of sixteen different
trigger sources. This capability allows this ADC to
sample and convert analog inputs that are associated
with PWM generators operating on independent time
bases.
19.1 Features Overview
The ADC module comprises the following features:
• 10-bit resolution
• Unipolar inputs
• Up to two Successive Approximation Registers
(SARs)
The user application typically requires synchronization
between analog data sampling and PWM output to the
application circuit. The very high-speed operation of
this ADC module allows “data on demand”.
• Up to 12 external input channels
• Up to two internal analog inputs
• Dedicated result register for each analog input
• ±1 LSB accuracy at 3.3V
In addition, several hardware features have been
added to the peripheral interface to improve real-time
performance in a typical DSP based application.
• Single supply operation
• 4 Msps conversion rate at 3.3V (devices with two
SARs)
• Result alignment options
• Automated sampling
• 2 Msps conversion rate at 3.3V (devices with one
SAR)
• External conversion start control
• Low-power CMOS technology
• Two internal inputs to monitor 1.2V internal
reference and EXTREF input signal
A block diagram of the ADC module is shown in
Figure 19-6.

The ADC module uses the following control and status
registers:
19.3 Module Functionality
The high-speed 10-bit ADC module is designed to
support power conversion applications when used with
the High-Speed PWM module. The ADC may have one
or two SAR modules, depending on the device variant.
If two SARs are present on a device, two conversions
can be processed at a time, yielding 4 Msps conversion
rate. If only one SAR is present on a device, only one
conversion can be processed at a time, yielding 2 Msps
conversion rate. The high-speed 10-bit ADC produces
two 10-bit conversion results in a 0.5 microsecond.
• ADCON: A/D Control Register
• ADSTAT: A/D Status Register
• ADBASE: A/D Base Register(1,2)
• ADPCFG: A/D Port Configuration Register
• ADCPC0: A/D Convert Pair Control Register 0
• ADCPC1: A/D Convert Pair Control Register 1
• ADCPC2: A/D Convert Pair Control Register 2(1)
• ADCPC3: A/D Convert Pair Control Register 3(1)
The ADCON register controls the operation of the
ADC module. The ADSTAT register displays the
status of the conversion processes. The ADPCFG
registers configure the port pins as analog inputs or
as digital I/O. The ADCPCx registers control the
triggering of the ADC conversions. See Register 19-1
through Register 19-8 for detailed bit configurations.
The ADC module supports up to 12 external analog
inputs and two internal analog inputs. To monitor
reference voltage, two internal inputs, AN12 and AN13,
are connected to the EXTREF and internal band gap
voltages (1.2V), respectively.
The analog reference voltage is defined as the device
supply voltage (AVDD/AVSS).
Note:
A unique feature of the ADC module is its
ability to sample inputs in an
asynchronous manner. Individual sample
and hold circuits can be triggered
independently of each other.

currently busy with an existing conversion process. If the shared S&H is busy at the time the
dedicated S&H is sampled, then the shared S&H will sample at the start of the new conversion
cycle.
Note 1: This control bit can only be changed while ADC is disabled (ADON = 0), and only applies to single SAR

ADBASE<15:1>: This register contains the base address of the user’s ADC Interrupt Service Routine
jump table. This register, when read, contains the sum of the ADBASE register contents and the
encoded value of the PxRDY status bits.
The encoder logic provides the bit number of the highest priority PxRDY bits where P0RDY is the
highest priority, and P6RDY is the lowest priority.
bit 0
Unimplemented: Read as ‘0’
Note 1: The encoding results are shifted left two bits so bits 1-0 of the result are always zero.
2: As an alternative to using the ADBASE Register, the ADCP0-6 ADC Pair Conversion Complete Interrupts
can be used to invoke A to D conversion completion routines for individual ADC input pairs.

20.2 Module Description
Figure 20-1 shows a functional block diagram of one
analog comparator from the SMPS comparator
module. The analog comparator provides high-speed
operation with a typical delay of 20 ns. The comparator
has a typical offset voltage of ±5 mV. The negative
input of the comparator is always connected to the
DAC circuit. The positive input of the comparator is
connected to an analog multiplexer that selects the
desired source pin.
The dsPIC33F SMPS Comparator module monitors
current and/or voltage transients that may be too fast
for the CPU and ADC to capture.
20.1 Features Overview
The SMPS comparator module offers the following
major features:
• 16 selectable comparator inputs
• Up to four analog comparators
• 10-bit DAC for each analog comparator
• Programmable output polarity
The analog comparator input pins are typically shared
with pins used by the Analog-to-Digital Converter
(ADC) module. Both the comparator and the ADC can
use the same pins at the same time. This capability
enables a user to measure an input voltage with the
ADC and detect voltage transients with the
comparator.
• Interrupt generation capability
• DACOUT pin to provide DAC output

20.3 Module Applications
20.5 Interaction with I/O Buffers
This module provides a means for the SMPS dsPIC
DSC devices to monitor voltage and currents in a
power conversion application. The ability to detect
transient conditions and stimulate the dsPIC DSC
processor and/or peripherals, without requiring the
processor and ADC to constantly monitor voltages or
currents, frees the dsPIC DSC to perform other tasks.
If the comparator module is enabled and a pin has
been selected as the source for the comparator, then
the chosen I/O pad must disable the digital input buffer
associated with the pad to prevent excessive currents
in the digital buffer due to analog input voltages.
20.6 Digital Logic
The comparator module has a high-speed comparator
and an associated 10-bit DAC that provides a
programmable reference voltage to the inverting input
of the comparator. The polarity of the comparator out-
put is user-programmable. The output of the module
can be used in the following modes:
The CMPCONx register (see Register 20-1) provides
the control logic that configures the comparator
module. The digital logic provides a glitch filter for the
comparator output to mask transient signals in less
than two instruction cycles. In Sleep or Idle mode, the
glitch filter is bypassed to enable an asynchronous
path from the comparator to the interrupt controller.
This asynchronous path can be used to wake-up the
processor from Sleep or Idle mode.
• Generate an Interrupt
• Trigger an ADC Sample and Convert Process
• Truncate the PWM Signal (current limit)
• Truncate the PWM Period (current minimum)
• Disable the PWM Outputs (Fault latch)
The comparator can be disabled while in Idle mode if
the CMPSIDL bit is set. If a device has multiple
comparators, if any CMPSIDL bit is set, then the entire
group of comparators will be disabled while in Idle
mode. This behavior reduces complexity in the design
of the clock control logic for this module.
The output of the comparator module may be used in
multiple modes at the same time, such as: (1)
generate an interrupt, (2) have the ADC take a sample
and convert it, and (3) truncate the PWM output in
response to a voltage being detected beyond its
expected value.
The digital logic also provides a one TCY width pulse
generator for triggering the ADC and generating
interrupt requests.
The comparator module can also be used to wake-up
the system from Sleep or Idle mode when the analog
input voltage exceeds the programmed threshold
voltage.
The CMPDACx (see Register 20-2) register provides
the digital input value to the reference DAC.
If the module is disabled, the DAC and comparator are
disabled to reduce power consumption.
20.4 DAC
20.7 Comparator Input Range
The range of the DAC is controlled via an analog
multiplexer that selects either AVDD/2, internal 1.2V,
1% reference, or an external reference source,
EXTREF. The full range of the DAC (AVDD/2) will
typically be used when the chosen input source pin is
shared with the ADC. The reduced range option
(INTREF) will likely be used when monitoring current
levels using a current sense resistor. Usually, the
measured voltages in such applications are small
(<1.25V); therefore the option of using a reduced
reference range for the comparator extends the
available DAC resolution in these applications. The
use of an external reference enables the user to
The comparator has a limitation for the input Common
Mode Range (CMR) of (AVDD – 1.5V), typical. This
means that both inputs should not exceed this range.
As long as one of the inputs is within the Common
Mode Range, the comparator output will be correct.
However, any input exceeding the CMR limitation will
cause the comparator input to be saturated.
If both inputs exceed the CMR, the comparator output
will be indeterminate.
20.8 DAC Output Range
The DAC has a limitation for the maximum reference
voltage input of (AVDD – 1.6) volts. An external
reference voltage input should not exceed this value or
the reference DAC output will become indeterminate.
connect to
application.
a reference that better suits their
DACOUT, shown in Figure 20-1, can only be
associated with a single comparator at a given time.
20.9 Comparator Registers
Note:
It should be ensured in software that
multiple DACOE bits are not set. The
output on the DACOUT pin will be indeter-
minate if multiple comparators enable the
DAC output.
The comparator module is controlled by the following
registers:
• CMPCONx: Comparator Control Register
• CMPDACx: Comparator DAC Control Register

21.0 SPECIAL FEATURES
The Configuration bits can be programmed (read
as ‘0’), or left unprogrammed (read as ‘1’), to select
various device configurations. These bits are mapped
starting at program memory location 0xF80000.
Note:
This data sheet summarizes the features
of the dsPIC33FJ06GS101/X02 and
dsPIC33FJ16GSX02/X04 devices. It is
not intended to be a comprehensive

information in this data sheet, refer to the
“dsPIC33F Family Reference Manual”.
Please see the Microchip web site

sections.
The individual Configuration bit descriptions for the
FBS, FGS, FOSCSEL, FOSC, FWDT, FPOR and FICD
Configuration registers are shown in Table 21-2.
Note that address, 0xF80000, is beyond the user pro-
gram memory space. It belongs to the configuration
memory space (0x800000-0xFFFFFF), which can only
be accessed using table reads and table writes.

The upper byte of all device Configuration registers
should always be ‘1111 1111’. This makes them
appear to be NOPinstructions in the remote event that
their locations are ever executed by accident. Since
Configuration bits are not implemented in the
corresponding locations, writing ‘1’s to these locations
has no effect on device operation.
dsPIC33FJ16GSX02/X04 devices include several
features intended to maximize application flexibility and
reliability, and minimize cost through elimination of
external components. These are:
• Flexible Configuration
• Watchdog Timer (WDT)
To prevent inadvertent configuration changes during
code execution, all programmable Configuration bits
are write-once. After a bit is initially programmed during
a power cycle, it cannot be written to again. Changing
a device configuration requires that power to the device
be cycled.
• Code Protection and CodeGuard™ Security
• JTAG Boundary Scan Interface
• In-Circuit Serial Programming™ (ICSP™)
• In-Circuit Emulation
• Brown-out Reset (BOR)

The

and
The Brown-out Reset (BOR) module is based on an
internal voltage reference circuit that monitors the
regulated supply voltage VCAP/VDDCORE. 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 (for example, 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).
dsPIC33FJ16GSX02/X04 devices power their core digital
logic at a nominal 2.5V. This can create a conflict for
designs that are required to operate at a higher typical
voltage, such as 3.3V. To simplify system design, all

dsPIC33FJ06GS101/X02
and
dsPIC33FJ16GSX02/X04 families incorporate an on-chip
regulator that allows the device to run its core logic from
VDD.
The regulator provides power to the core from the other
VDD pins. When the regulator is enabled, a low-ESR
(less than 5 ohms) capacitor (such as tantalum or
ceramic) must be connected to the VCAP/VDDCORE pin
(Figure 21-1). This helps to maintain the stability of the
regulator. The recommended value for the filter
capacitor is provided in Table 24-13 located in
Section 24.1 “DC Characteristics”.
A BOR generates a Reset pulse, which resets the
device. The BOR selects the clock source, based on
the device Configuration bit values (FNOSC<2:0> and
POSCMD<1:0>).
If an oscillator mode is selected, the BOR activates the
Oscillator Start-up Timer (OST). The system clock is
held until OST expires. If the PLL is used, the clock is
held until the LOCK bit (OSCCON<5>) is ‘1’.
Note:
It is important for the low-ESR capacitor to
be placed as close as possible to the
VCAP/VDDCORE pin.
Concurrently, the PWRT time-out (TPWRT) is applied
before the internal Reset is released. If TPWRT = 0and
a crystal oscillator is being used, then a nominal delay
of TFSCM = 100 is applied. The total delay in this case
is TFSCM.
On a POR, it takes approximately 20 μs for the on-chip
voltage regulator to generate an output voltage. During
this time, designated as TSTARTUP, code execution is
disabled. TSTARTUP is applied every time the device
resumes operation after any power-down.
The BOR Status bit (RCON<1>) is set to indicate that a
BOR has occurred. The BOR circuit continues to
operate while in Sleep or Idle modes and resets the
device should VDD fall below the BOR threshold
voltage.

21.4.2
SLEEP AND IDLE MODES
21.4 Watchdog Timer (WDT)
If the WDT is enabled, it will continue to run during
Sleep or Idle modes. When the WDT time-out occurs,
the device will wake the device and code execution will
continue from where the PWRSAV instruction was
executed. The corresponding SLEEP or IDLE bits
(RCON<3:2>) will need to be cleared in software after
the device wakes up.
For
dsPIC33FJ06GS101/X02
and
dsPIC33FJ16GSX02/X04 devices, the WDT is driven by
the LPRC oscillator. When the WDT is enabled, the clock
source is also enabled.
21.4.1
PRESCALER/POSTSCALER
The nominal WDT clock source from LPRC is 32 kHz.
This feeds a prescaler than can be configured for either
5-bit (divide-by-32) or 7-bit (divide-by-128) operation.
The prescaler is set by the WDTPRE Configuration bit.
With a 32 kHz input, the prescaler yields a nominal
WDT time-out period (TWDT) of 1 ms in 5-bit mode, or
4 ms in 7-bit mode.
21.4.3
ENABLING WDT
The WDT is enabled or disabled by the FWDTEN
Configuration bit in the FWDT Configuration register.
When the FWDTEN Configuration bit is set, the WDT is
always enabled.
The WDT can be optionally controlled in software when
the FWDTEN Configuration bit has been programmed
to ‘0’. The WDT is enabled in software by setting the
SWDTEN control bit (RCON<5>). The SWDTEN
control bit is cleared on any device Reset. The software
WDT option allows the user application to enable the
WDT for critical code segments and disable the WDT
during non-critical segments for maximum power
savings.
A variable postscaler divides down the WDT prescaler
output and allows for a wide range of time-out periods.
The postscaler is controlled by the WDTPOST<3:0>
Configuration bits (FWDT<3:0>) which allow the
selection of 16 settings, from 1:1 to 1:32,768. Using the
prescaler and postscaler, time-out periods ranging from
1 ms to 131 seconds can be achieved.
The WDT, prescaler and postscaler are reset:
• On any device Reset
Note:
If the WINDIS bit (FWDT<6>) is cleared, the
CLRWDTinstruction should be executed by
the application software only during the last
1/4 of the WDT period. This CLRWDT
window can be determined by using a timer.
If a CLRWDTinstruction is executed before
this window, a WDT Reset occurs.
• On the completion of a clock switch, whether
invoked by software (i.e., setting the OSWEN bit
after changing the NOSC bits) or by hardware
(i.e., Fail-Safe Clock Monitor)
• When a PWRSAVinstruction is executed
(i.e., Sleep or Idle mode is entered)
• When the device exits Sleep or Idle mode to
resume normal operation
The WDT flag bit, WDTO (RCON<4>), is not automatically
cleared following a WDT time-out. To detect subsequent
WDT events, the flag must be cleared in software.
• By a CLRWDTinstruction during normal execution
Note:
The CLRWDT and PWRSAV instructions
clear the prescaler and postscaler counts
when executed.

with MPLAB IDE. Debugging functionality is controlled
through the EMUCx (Emulation/Debug Clock) and
EMUDx (Emulation/Debug Data) pin functions.
dsPIC33FJ16GSX02/X04 devices implement a JTAG
interface, which supports boundary scan device test-
ing, as well as in-circuit programming. Detailed infor-
mation on this interface will be provided in future

digital
controllers can be serially programmed while in the end
application circuit. This is done with two lines for clock
and data and three other lines for power, ground and
the programming sequence. Serial programming
allows customers to manufacture boards with
unprogrammed devices and then program the digital
signal controller just before shipping the product. Serial
programming also allows the most recent firmware or a
custom firmware to be programmed. Refer to the
“dsPIC33F/PIC24H Flash Programming Specification”
(DS70152) for details about In-Circuit Serial
Programming (ICSP).
To use the in-circuit debugger function of the device,
the design must implement ICSP connections to
MCLR, VDD, VSS, and the PGECx/PGEDx pin pair. In
addition, when the feature is 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.
Any of the three pairs of programming clock/data pins
can be used:

rotate/shift instructions) have two operands:
22.0 INSTRUCTION SET SUMMARY
Note:
This data sheet summarizes the features
of the dsPIC33FJ06GS101/X02 and
dsPIC33FJ16GSX02/X04 devices. It is
not intended to be a comprehensive
reference source. To complement the
information in this data sheet, refer to the
“dsPIC33F Family Reference Manual”.
Please see the Microchip web site
(www.microchip.com) for the latest
“dsPIC33F Family Reference Manual”
sections.
• 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 can
use some of the following operands:
• A literal value to be loaded into a W register or file
register (specified by ‘k’)
• The W register or file register where the literal
value is to be loaded (specified by ‘Wb’ or ‘f’)
The dsPIC33F instruction set is identical to that of the
dsPIC30F.
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
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 second source operand, which is a literal
value
• 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 can use some of the
following operands:
• Word or byte-oriented operations
• Bit-oriented operations
• Literal operations
• The accumulator (A or B) to be used (required
operand)
• DSP operations
• 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
• Control operations
Table 22-1 shows the general symbols used in
describing the instructions.
The dsPIC33F instruction set summary in Table 22-2
lists all the instructions, along with the status flags
affected by each instruction.
The other DSP instructions do not involve any
multiplication and can include:
• The accumulator to be used (required)
Most word or byte-oriented W register instructions
(including barrel shift instructions) have three
operands:
• The source or destination operand (designated as
Wso or Wdo, respectively) with or without an
address modifier
• The first source operand, which is typically a
register ‘Wb’ without any address modifier
• The amount of shift specified by a W register,
‘Wn’, or a literal value
• The second source operand, which is typically a
register ‘Ws’ with or without an address modifier
The control instructions can use some of the following
operands:
• The destination of the result, which is typically a
register ‘Wd’ with or without an address modifier
• A program memory address
However, word or byte-oriented file register instructions
have two operands:
• The mode of the table read and table write
instructions
• The file register specified by the value, ‘f’
• The destination, which could be either the file
register, ‘f’, or the W0 register, which is denoted
as ‘WREG’

Most instructions are
a
single word. Certain
executed as a NOP. Notable exceptions are the BRA
(unconditional/computed branch), indirect CALL/GOTO,
all table reads and writes and 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.
double-word instructions are designed to provide all the
required information 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.
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)

23.5 MPLAB ASM30 Assembler, Linker
and Librarian
The MPASM Assembler is a full-featured, universal
macro assembler for all PIC MCUs.
MPLAB ASM30 Assembler produces relocatable
machine code from symbolic assembly language for
dsPIC30F devices. MPLAB C30 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:
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.
The MPASM Assembler features include:
• Integration into MPLAB IDE projects
• Support for the entire dsPIC30F instruction set
• Support for fixed-point and floating-point data
• Command line interface
• User-defined macros to streamline
assembly code
• Rich directive set
• Conditional assembly for multi-purpose
source files
• Flexible macro language
• MPLAB IDE compatibility
• Directives that allow complete control over the
assembly process
23.6 MPLAB SIM Software Simulator
23.3 MPLAB C18 and MPLAB C30
C Compilers
The MPLAB SIM Software Simulator allows code
development in
a
PC-hosted environment by
simulating 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.
The MPLAB C18 and MPLAB C30 Code Development
Systems are complete ANSI
C
compilers for
Microchip’s PIC18 and PIC24 families of microcon-
trollers and the dsPIC30 and dsPIC33 family of digital
signal controllers. These compilers provide powerful
integration capabilities, superior code optimization and
ease of use not found with other compilers.
For easy source level debugging, the compilers provide
symbol information that is optimized to the MPLAB IDE
debugger.
The MPLAB SIM Software Simulator fully supports
symbolic debugging using the MPLAB C18 and
MPLAB C30 C Compilers, and the MPASM and
MPLAB ASM30 Assemblers. The software simulator
offers the flexibility to develop and debug code outside
of the hardware laboratory environment, making it an
excellent, economical software development tool.
23.4 MPLINK Object Linker/
MPLIB Object Librarian
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.
The object linker/library features include:
• Efficient linking of single libraries instead of linking
many smaller files
• Enhanced code maintainability by grouping
related modules together
• Flexible creation of libraries with easy module
listing, replacement, deletion and extraction

pulled to VSS. WDT, etc., are all switched off, and VREGS (RCON<8>) = 1.
3: The Δ current is the additional current consumed when the WDT module is enabled. This current should
be added to the base IPD current.
4: These currents are measured on the device containing the most memory in this family.
