Memory
SINGLE-CHIP 16-BIT CMOS MICROCOMPUTER
Operation of Functional Blocks
The M30221 group accommodates certain units in a single chip. These units include ROM and RAM to
store instructions and data and the central processing unit (CPU) to execute arithmetic/logic operations.
Also included are peripheral units such as timers, real time port, serial I/O, LCD drive control circuit, D-A
converter, A-D converter, DMAC and I/O ports.
Memory
Figure 1.4.1 is a memory map of the M30221 group. The address space extends the 1M bytes from ad-
dress 0000016 to FFFFF16. From FFFFF16 down is ROM. For example, in the M30221M3-XXXFP, there is
24K bytes of internal ROM from FA00016 to FFFFF16. The vector table for fixed interrupts such as the reset
_______
and NMI are mapped to FFFDC16 to FFFFF16. The starting address of the interrupt routine is stored here.
The address of the vector table for timer interrupts, etc., can be set as desired using the internal register
(INTB). See the section on interrupts for details.
From 0040016 up is RAM. For example, in the M30221M3-XXXFP, 1.5K bytes of internal RAM is mapped
to the space from 0040016 to 009FF6. In addition to storing data, the RAM also stores the stack used when
calling subroutines and when interrupts are generated.
The SFR area is mapped to 0000016 to 003FF16. This area accommodates the control registers for periph-
eral devices such as I/O ports, A-D converter, serial I/O, timers, and LCD, etc. Figures 1.7.1 to 1.7.3 are
location of peripheral unit control registers. Any part of the SFR area that is not occupied is reserved and
cannot be used for other purposes.
The special page vector table is mapped to FFE0016 to FFFDB16. If the starting addresses of subroutines
or the destination addresses of jumps are stored here, subroutine call instructions and jump instructions
can be used as 2-byte instructions, reducing the number of program steps.

Figure 1.5.1. Central processing unit register
(1) Data registers (R0, R0H, R0L, R1, R1H, R1L, R2, and R3)
Data registers (R0, R1, R2, and R3) are configured with 16 bits, and are used primarily for transfer and
arithmetic/logic operations.
Registers R0 and R1 each can be used as separate 8-bit data registers, high-order bits as (R0H/R1H),
and low-order bits as (R0L/R1L). In some instructions, registers R2 and R0, as well as R3 and R1 can
use as 32-bit data registers (R2R0/R3R1).
(2) Address registers (A0 and A1)
Address registers (A0 and A1) are configured with 16 bits, and have functions equivalent to those of data
registers. These registers can also be used for address register indirect addressing and address register
relative addressing.
In some instructions, registers A1 and A0 can be combined for use as a 32-bit address register (A1A0).

(3) Frame base register (FB)
Frame base register (FB) is configured with 16 bits, and is used for FB relative addressing.
(4) Program counter (PC)
Program counter (PC) is configured with 20 bits, indicating the address of an instruction to be executed.
(5) Interrupt table register (INTB)
Interrupt table register (INTB) is configured with 20 bits, indicating the start address of an interrupt vector
table.
(6) Stack pointer (USP/ISP)
Stack pointer comes in two types: user stack pointer (USP) and interrupt stack pointer (ISP), each config-
ured with 16 bits.
Your desired type of stack pointer (USP or ISP) can be selected by a stack pointer select flag (U flag).
This flag is located at the position of bit 7 in the flag register (FLG).
(7) Static base register (SB)
Static base register (SB) is configured with 16 bits, and is used for SB relative addressing.
(8) Flag register (FLG)
Flag register (FLG) is configured with 11 bits, each bit is used as a flag. Figure 1.5.2 shows the flag
register (FLG). The following explains the function of each flag:
• Bit 0: Carry flag (C flag)
This flag retains a carry, borrow, or shift-out bit that has occurred in the arithmetic/logic unit.
• Bit 1: Debug flag (D flag)
This flag enables a single-step interrupt.
When this flag is “1”, a single-step interrupt is generated after instruction execution. This flag is
cleared to “0” when the interrupt is acknowledged.
• Bit 2: Zero flag (Z flag)
This flag is set to “1” when an arithmetic operation resulted in 0; otherwise, cleared to “0”.
• Bit 3: Sign flag (S flag)
This flag is set to “1” when an arithmetic operation resulted in a negative value; otherwise, cleared to “0”
.
• Bit 4: Register bank select flag (B flag)
This flag chooses a register bank. Register bank 0 is selected when this flag is “0” ; register bank 1 is
selected when this flag is “1”.
• Bit 5: Overflow flag (O flag)
This flag is set to “1” when an arithmetic operation resulted in overflow; otherwise, cleared to “0”.
• Bit 6: Interrupt enable flag (I flag)
This flag enables a maskable interrupt.
An interrupt is disabled when this flag is “0”, and is enabled when this flag is “1”. This flag is cleared to
“0” when the interrupt is acknowledged.

• Bit 7: Stack pointer select flag (U flag)
Interrupt stack pointer (ISP) is selected when this flag is “0” ; user stack pointer (USP) is selected
when this flag is “1”.
This flag is cleared to “0” when a hardware interrupt is acknowledged or an INT instruction of software
interrupt Nos. 0 to 31 is executed.
• Bits 8 to 11: Reserved area
• Bits 12 to 14: Processor interrupt priority level (IPL)
Processor interrupt priority level (IPL) is configured with three bits, for specification of up to eight
processor interrupt priority levels from level 0 to level 7.
If a requested interrupt has priority greater than the processor interrupt priority level (IPL), the interrupt
is enabled.
• Bit 15: Reserved area
The C, Z, S, and O flags are changed when instructions are executed. See the software manual for
details.

Reset
SINGLE-CHIP 16-BIT CMOS MICROCOMPUTER
Reset
There are two kinds of resets; hardware and software. In both cases, operation is the same after the reset.
(See “Software Reset” for details of software resets.) This section explains on hardware resets.
When the supply voltage is in the range where operation is guaranteed, a reset is effected by holding the
reset pin level “L” (0.2VCC max.) for at least 20 cycles. When the reset pin level is then returned to the “H”
level while main clock is stable, the reset status is cancelled and program execution resumes from the
address in the reset vector table.
Figure 1.6.1 shows the example reset circuit. Figure 1.6.2 shows the reset sequence.

Programmable I/O Port
SINGLE-CHIP 16-BIT CMOS MICROCOMPUTER
Programmable I/O Ports
There are 83 programmable I/O ports: P0 to P13 (excluding P77). Each port can be set independently for
input or output using the direction register. A pull-up resistance for each block of 4 ports can be set. P77 is
an input-only port and has no built-in pull-up resistance.
Figures 1.19.1 to 1.19.4 show the programmable I/O ports. Figure 1.19.5 shows the I/O pins.
Each pin functions as a programmable I/O port and as the I/O for the built-in peripheral devices.
To use the pins as the inputs for the built-in peripheral devices, set the direction register of each pin to input
mode. When the pins are used as the outputs for the built-in peripheral devices (other than the D-A con-
verter), they function as outputs regardless of the contents of the direction registers. When pins are to be
used as the outputs for the D-A converter, do not set the direction registers to output mode.
(1) Direction registers
These registers are used to choose the direction of the programmable I/O ports. Each bit in these regis-
ters corresponds one for one to each I/O pin.
Note: There is no direction register bit for P77.
(2) Port registers
These registers are used to write and read data for input and output to and from an external device. A
port register consists of a port latch to hold output data and a circuit to read the status of a pin. Each bit
in port registers corresponds one for one to each I/O pin.
(3) Pull-up control registers
The pull-up control register can be set to apply a pull-up resistance to each block of 4 ports. When ports
are set to have a pull-up resistance, the pull-up resistance is connected only when the direction register is
set for input. The pull-up resistance is not connected for pins that are set for output from peripheral
functions, regardless of the setting in the pull-up control register. When pull-up is ON for ports P1 and P2,
an intermittent pull-up that pulls up the port for only a set period of time, can be performed from the key
input mode register.
(4) Key input mode register
With bits 0 and 1 of this register, it is possible to select both edges or the fall edge of the key input for P1
and P2. Also, with bit 2, it is possible to make the pull-up for a port (P1 or P2), which is set for pull-up using
the pull-up control register, automatically connect as an intermittent pull-up. And, using the significant 3
bits, the pull-up resistance can be connected to and disconnected from ports P12 and P13.
(5) Real-time port control register
The real-time port control register can be used to set the registers of ports P0, P1, P2 and P12 for real-
time port output, whereby output is synchronized with timer overflow of timers A0, A1, A5 and A6 in the
timer mode.

Usage precaution
SINGLE-CHIP 16-BIT CMOS MICROCOMPUTER
Usage Precaution
Timer A (timer mode)
(1) Reading the timer Ai register while a count is in progress allows reading, with arbitrary timing, the
value of the counter. Reading the timer Ai register with the reload timing gets “FFFF16”. Reading the
timer Ai register after setting a value in the timer Ai register with a count halted but before the counter
starts counting gets a proper value.
Timer A (event counter mode)
(1) Reading the timer Ai register while a count is in progress allows reading, with arbitrary timing, the
value of the counter. Reading the timer Ai register with the reload timing gets “FFFF16” by underflow
or “000016” by overflow. Reading the timer Ai register after setting a value in the timer Ai register with
a count halted but before the counter starts counting gets a proper value.
(2) When stop counting in free run type, set timer again.
Timer A (one-shot timer mode)
(1) Setting the count start flag to “0” while a count is in progress causes as follows:
• The counter stops counting and a content of reload register is reloaded.
• The TAiOUT pin outputs “L” level.
• The interrupt request generated and the timer Ai interrupt request bit goes to “1”.
(2) The timer Ai interrupt request bit goes to “1” if the timer's operation mode is set using any of the
following procedures:
• Selecting one-shot timer mode after reset.
•Changing operation mode from timer mode to one-shot timer mode.
• Changing operation mode from event counter mode to one-shot timer mode.
Therefore, to use timer Ai interrupt (interrupt request bit), set timer Ai interrupt request bit to “0”
after the above listed changes have been made.
Timer A (pulse width modulation mode)
(1) The timer Ai interrupt request bit becomes “1” if setting operation mode of the timer in compliance with
any of the following procedures:
• Selecting PWM mode after reset.
•Changing operation mode from timer mode to PWM mode.
•Changing operation mode from event counter mode to PWM mode.
Therefore, to use timer Ai interrupt (interrupt request bit), set timer Ai interrupt request bit to “0”
after the above listed changes have been made.
(2) Setting the count start flag to “0” while PWM pulses are being output causes the counter to stop
counting. If the TAiOUT pin is outputting an “H” level in this instance, the output level goes to “L”, and
the timer Ai interrupt request bit goes to “1”. If the TAiOUT pin is outputting an “L” level in this instance,
the level does not change, and the timer Ai interrupt request bit does not becomes “1”.
Timer B (timer mode, event counter mode)
(1) Reading the timer Bi register while a count is in progress allows reading , with arbitrary timing, the
value of the counter. Reading the timer Bi register with the reload timing gets “FFFF16”. Reading the
timer Bi register after setting a value in the timer Bi register with a count halted but before the counter
starts counting gets a proper value.
24
Mitsubishi microcomputers
M30221 Group
Usage precaution
SINGLE-CHIP 16-BIT CMOS MICROCOMPUTER
Timer B (pulse period/pulse width measurement mode)
(1) If changing the measurement mode select bit is set after a count is started, the timer Bi interrupt
request bit goes to “1”.
(2) When the first effective edge is input after a count is started, an indeterminate value is transferred to
the reload register. At this time, timer Bi interrupt request is not generated.
Real time port
(1) Make sure timer Ai for real time port output is set for timer mode, and is set to have “no gate function”
using the gate function select bit.
(2) Before setting the real time port mode select bit to “1”, temporarily turn off the timer Ai used and write
its set value to the timer Ai register.
Sirial I/O
(1) In case IIC mode select bit (bit 0 of address 037716) is set to "1" with UART2.When setting up port
direction P7 (address 03EF16), write immediate values. If you use Read/Modify/Write instructions
(BSET,BCLR,AND,OR,etc..) on the P7 direction register, the value of P71 direction register may
change to unknown data.
(2) MASK ROM version ONRY when IIC mode select bit (bit 0 of address 037716) and the internal/
external select bit (bit 3 of address 037816) are both set to "1". The function of "SCL wait output bit 2
(bit 5 of address 037616)" dose not work.
(3) MASK ROM version ONRY when IIC mode select bit (bit 0 of address 037716) and the internal/
external select bit (bit 3 of address 037816) are both set to "1". According to the datasheet, when IICM
is set to "1", the port terminal is readable by the CPU even though "1" is assigned to P71 of the
direction register. However, the CPU cannot read port P71 data if the P71 direction register is set to
"1".
A-D Converter
(1) Write to each bit (except bit 6) of A-D control register 0, to each bit of A-D control register 1, and to bit
0 of A-D control register 2 when A-D conversion is stopped (before a trigger occurs).
In particular, when the Vref connection bit is changed from “0” to “1”, start A-D conversion after an
elapse of 1 µs or longer.
(2) When changing A-D operation mode, select analog input pin again.
(3) Using one-shot mode or single sweep mode
Read the correspondence A-D register after confirming A-D conversion is finished. (It is known by A-
D conversion interrupt request bit.)
(4) Using repeat mode, repeat sweep mode 0 or repeat sweep mode 1
Use the undivided main clock as the internal CPU clock.
Stop Mode and Wait Mode
____________
(1) When returning from stop mode by hardware reset, RESET pin must be set to “L” level until main clock
oscillation is stabilized.
(2) When switching to either wait mode or stop mode, instructions occupying four bytes either from the
WAIT instruction or from the instruction that sets the every-clock stop bit to “1” within the instruction
queue are prefetched and then the program stops. So put at least four NOPs in succession either to
the WAIT instruction or to the instruction that sets the every-clock stop bit to “1”.
(3) When the MCU running in low-speed or low power dissipation mode, do not enter WAIT mode with
peripheral function clock stop bit (CM02) set to "1".

Usage precaution
SINGLE-CHIP 16-BIT CMOS MICROCOMPUTER
Interrupts
(1) Reading address 0000016
• When maskable interrupt is occurred, CPU read the interrupt information (the interrupt number
and interrupt request level) in the interrupt sequence.
The interrupt request bit of the certain interrupt written in address 0000016 will then be set to “0”.
Reading address 0000016 by software sets enabled highest priority interrupt source request bit to “0”.
Though the interrupt is generated, the interrupt routine may not be executed.
Do not read address 0000016 by software.
(2) Setting the stack pointer
• The value of the stack pointer immediately after reset is initialized to 000016. Accepting an
interrupt before setting a value in the stack pointer may become a factor of runaway. Be sure to
set a value in the stack pointer before accepting an interrupt.
_______
When using the NMI interrupt, initialize the stack point at the beginning of a program. Concerning
_______
the first instruction immediately after reset, generating any interrupts including the NMI interrupt is
prohibited.
_______
(3) The NMI interrupt
_______
_______
• The NMI interrupt can not be disabled. Be sure to connect NMI pin to Vcc via a pull-up resistor if
unused.
_______
• Do not get either into stop mode with the NMI pin set to “L”.
(4) External interrupt
• When the polarity of the INT0 to INT5 pins is changed, the interrupt request bit is sometimes set
to "1". After changing the polarity, set the interrupt request bit to "0".

M30221 Group
Usage precaution
SINGLE-CHIP 16-BIT CMOS MICROCOMPUTER
(5) Rewrite the interrupt control register
• To rewrite the interrupt control register, do so at a point that does not generate the interrupt
request for that register. If there is possibility of the interrupt request occur, rewrite the interrupt
control register after the interrupt is disabled. The program examples are described as follow:
Example 1:
INT_SWITCH1:
FCLR
I
; Disable interrupts.
AND.B #00h, 0055h ; Clear TA0IC int. priority level and int. request bit.
NOP
NOP
FSET
;
Four NOP instructions are required when using HOLD function.
I
; Enable interrupts.
Example 2:
INT_SWITCH2:
FCLR
I
; Disable interrupts.
AND.B #00h, 0055h ; Clear TA0IC int. priority level and int. request bit.
MOV.W MEM, R0
; Dummy read.
FSET
I
; Enable interrupts.
Example 3:
INT_SWITCH3:
PUSHC FLG
; Push Flag register onto stack
; Disable interrupts.
FCLR
I
AND.B #00h, 0055h ; Clear TA0IC int. priority level and int. request bit.
POPC FLG ; Enable interrupts.
• When a instruction to rewrite the interrupt control register is executed but the interrupt is disabled,
the interrupt request bit is not set sometimes even if the interrupt request for that register has
been generated. This will depend on the instruction. If this creates problems, use the below in-
structions to change the register.
Instructions : AND, OR, BCLR, BSET
