Refer to the table of 740 family addressing modes and machine instructions or the 740 Family Software Manual for details on the instruction set. Machine-resident 740 family instructions are as follows: The FST and SLW instruction cannot be used. The STP, WIT, MUL, and DIV instruction can be used. The central processing unit (CPU) has six registers. Figure 8 shows the 740 Family CPU register structure. [Accumulator (A)] The accumulator is an 8-bit register. Data operations such as arithmetic data transfer, etc., are executed mainly through the accumulator. The stack pointer is an 8-bit register used during subroutine calls and interrupts. This register indicates start address of stored area (stack) for storing registers during subroutine calls and interrupts. The low-order 8 bits of the stack address are determined by the contents of the stack pointer. The high-order 8 bits of the stack address are determined by the stack page selection bit. If the stack page selection bit is “0” , the high-order 8 bits becomes “0016”. If the stack page selection bit is “1”, the high-order 8 bits becomes “0116”. Figure 9 shows the operations of pushing register contents onto the stack and popping them from the stack. Table 6 shows the push and pop instructions of accumulator or processor status register. Store registers other than those described in Figure 9 with program when the user needs them during interrupts or subroutine calls. [Index Register X (X)] The index register X is an 8-bit register. In the index addressing modes, the value of the OPERAND is added to the contents of register X and specifies the real address. [Program Counter (PC)] The program counter is a 16-bit counter consisting of two 8-bit registers PCH and PCL. It is used to indicate the address of the next instruction to be executed. [Index Register Y (Y)] The index register Y is an 8-bit register. In partial instruction, the value of the OPERAND is added to the contents of register Y and specifies the real address. b0 b7 A Accumulator b0 b7 X Index register X b0 b7 Y b7 Index register Y b0 S b15 b7 PCH Stack pointer b0 Program counter PCL b7 b0 N V T B D I Z C Processor status register (PS) Carry flag Zero flag Interrupt disable flag Decimal mode flag Break flag Index X mode flag Overflow flag Negative flag Fig. 8 740 Family CPU register structure 10 MITSUBISHI MICROCOMPUTERS 7560 Group SINGLE-CHIP 8-BIT CMOS MICROCOMPUTER On-going Routine Interrupt request (Note) M (S) Execute JSR Push return address on stack M (S) (PCH) (S) (S) – 1 M (S) (PCL) (S) (S)– 1 M (S) (S) M (S) (S) Subroutine POP return address from stack (S) + 1 (PCL) M (S) (S) (S) + 1 (PCH) M (S) (S) – 1 (S) – 1 (PS) (S) – 1 Execute RTI Note: Condition for acceptance of an interrupt request here Push return address on stack (PCL) Interrupt Service Routine Execute RTS (S) (S) (PCH) (S) (S) + 1 (PS) M (S) (S) (S) + 1 (PCL) M (S) (S) (S) + 1 (PCH) M (S) Push contents of processor status register on stack I Flag is set from “0” to “1” Fetch the jump vector POP contents of processor status register from stack POP return address from stack Interrupt enable bit corresponding to each interrupt source is “1” Interrupt disable flag is “0” Fig. 9 Register push and pop at interrupt generation and subroutine call Table 6 Push and pop instructions of accumulator or processor status register Push instruction to stack Pop instruction from stack Accumulator PHA PLA Processor status register PHP PLP 11 MITSUBISHI MICROCOMPUTERS 7560 Group SINGLE-CHIP 8-BIT CMOS MICROCOMPUTER [Processor status register (PS)] The processor status register is an 8-bit register consisting of 5 flags which indicate the status of the processor after an arithmetic operation and 3 flags which decide MCU operation. Branch operations can be performed by testing the Carry (C) flag , Zero (Z) flag, Overflow (V) flag, or the Negative (N) flag. In decimal mode, the Z, V, N flags are not valid. • Bit 0: Carry flag (C) The C flag contains a carry or borrow generated by the arithmetic logic unit (ALU) immediately after an arithmetic operation. It can also be changed by a shift or rotate instruction. • Bit 1: Zero flag (Z) The Z flag is set to “1” if the result of an immediate arithmetic operation or a data transfer is “0”, and set to “0” if the result is anything other than “0”. • Bit 2: Interrupt disable flag (I) The I flag disables all interrupts except for the interrupt generated by the BRK instruction. Interrupts are disabled when the I flag is “1”. • Bit 3: Decimal mode flag (D) The D flag determines whether additions and subtractions are executed in binary or decimal. Binary arithmetic is executed when this flag is “0”; decimal arithmetic is executed when it is “1”. Decimal correction is automatic in decimal mode. Only the ADC and SBC instructions can be used for decimal arithmetic. • Bit 4: Break flag (B) The B flag is used to indicate that the current interrupt was generated by the BRK instruction. When the BRK instruction is generated, the B flag is set to “1” automatically. When the other interrupts are generated, the B flag is set to “0”, and the processor status register is pushed onto the stack. • Bit 5: Index X mode flag (T) When the T flag is “0”, arithmetic operations are performed between accumulator and memory. When the T flag is “1”, direct arithmetic operations and direct data transfers are enabled between memory locations. • Bit 6: Overflow flag (V) The V flag is used during the addition or subtraction of one byte of signed data. It is set to “1” if the result exceeds +127 to -128. When the BIT instruction is executed, bit 6 of the memory location operated on by the BIT instruction is stored in the V flag. • Bit 7: Negative flag (N) The N flag is set to “1” if the result of an arithmetic operation or data transfer is negative.

RAM RAM is used for data storage and for stack area of subroutine calls and interrupts. Zero Page The 256 bytes from addresses 000016 to 00FF 16 are called the zero page area. The internal RAM and the special function registers (SFR) are allocated to this area. The zero page addressing mode can be used to specify memory and register addresses in the zero page area. Access to this area with only 2 bytes is possible in the zero page addressing mode. Special Page ROM The first 128 bytes and the last 2 bytes of ROM are reserved for device testing and the rest is user area for storing programs. Interrupt Vector Area The 256 bytes from addresses FF0016 to FFFF16 are called the special page area. The special page addressing mode can be used to specify memory addresses in the special page area. Access to this area with only 2 bytes is possible in the special page addressing mode.

Ports P16, P17, P4, P5, P6, and P71–P77 can be set to input mode or output mode by each pin individually. P0 0–P07 and P10-P15 are respectively set to input mode or output mode in a lump by bit 0 of the direction registers of ports P0 and P1 (see Figure 13). When “0” is set to the bit corresponding to a pin, that pin becomes an input mode. When “1” is set to that bit, that pin becomes an output mode. If data is read from a port set to output mode, the value of the port latch is read, not the value of the pin itself. A port set to input mode is floating. If data is read from a port set to input mode, the value of the pin itself is read. If a pin set to input mode is written to, only the port latch is written to and the pin remains floating. b7 b0 Ports P00 to P07 direction register 0 : Input mode 1 : Output mode Not used (Undefined at reading) (If writing to these bits, write “0”.) b7 b0 Port P1 direction register (P1D : address 000316) Ports P10 to P15 direction register 0 : Input mode 1 : Output mode Not used (Undefined at reading) (If writing to these bits, write “0”.)

When an interrupt request is accepted, the program branches to the interrupt jump destination address set in the vector address (see Figure 10). By acceptance of an interrupt, the following operations are automatically performed: 1. The contents of the program counter and the processor status register are automatically pushed onto the stack. 2. The interrupt jump destination address is read from the vector table into the program counter. 3. The interrupt disable flag is set to “1” and the corresponding interrupt request bit is set to “0”. Interrupt Control Each interrupt is controlled by an interrupt request bit, an interrupt enable bit, and the interrupt disable flag except for the software interrupt set by the BRK instruction. An interrupt is accepted if the corresponding interrupt request and enable bits are “1” and the interrupt disable flag is “0”. Interrupt enable bits can be set to “0” or “1” by program. Interrupt request bits can be set to “0” by program, but cannot be set to “1” by program. The BRK instruction interrupt and reset cannot be disabled with any flag or bit. When the interrupt disable (I) flag is set to “1”, all interrupt requests except the BRK instruction interrupt and reset are not accepted. When several interrupt requests occur at the same time, the interrupts are received according to priority.

A Key input interrupt request is generated by applying “L” level voltage to any pin of port P2 of which key input interrupt is en- abled. In other words, it is generated when AND of input level goes from “1” to “0”. A connection example of using a key input interrupt is shown in Figure 22, where an interrupt request is generated by pressing one of the keys consisted as an active-low key matrix which inputs to ports P20–P23.

Timer X and timer Y are 16-bit timers, and timer 1, timer 2, and timer 3 are 8-bit timers. All timers are down count timers. When the timer reaches “0”, an underflow occurs at the next count pulse and the corresponding timer latch is reloaded into the timer and the count is continued. When a timer underflows, the interrupt request bit corresponding to that timer is set to “1”.

Except for this, the operation in event counter mode is the same as in timer mode. When using a timer in this mode, set the P5 4/ CNTR0 pin to input mode (set “0” to bit 4 of port P5 direction register). ●Timer X Write Control Which write control can be selected by the timer X write control bit (bit 0) of the timer X mode register (address 002716), writing data to both the latch and the timer at the same time or writing data only to the latch. When the operation “writing data only to the latch” is selected, the value is set to the timer latch by writing data to the timer X register and the timer is updated at next underflow. After reset, the operation “writing data to both the latch and the timer at the same time” is selected, and the value is set to both the latch and the timer at the same time by writing data to the timer X register. The write operation is independent of timer X count operation, operating or stopping. When the value is written in latch only, a value is simultaneously set to the timer X and the timer X latch if the writing in the highorder register and the underflow of timer X are performed at the same timing. Unexpected value may be set in the high-order timer on this occasion. ●Real Time Port Control While the real time port function is valid, data for the real time port are output from ports P5 2 and P5 3 each time the timer X underflows. (However, if the real time port control bit is changed from “0” to “1” after set of the real time port data, data are output independent of the timer X operation.) If the data for the real time port is changed while the real time port function is valid, the changed data are output at the next underflow of timer X. Before using this function, set the P52 /RTP 0, P5 3/RTP1 pins to output mode (set “1” to bits 2, 3 of port P5 direction register). (4) Pulse width measurement mode ■Note on CNTR0 interrupt active edge selection The count source is f(XIN)/16 (or f(XCIN)/16 in low-speed mode). If CNTR 0 active edge switch bit is “0”, the timer counts while the input signal of CNTR 0 pin is at “H”. If it is “1”, the timer counts while the input signal of CNTR0 pin is at “L”. When using a timer in this mode, set the P54/CNTR0 pin to input mode (set “0” to bit 4 of port P5 direction register). CNTR0 interrupt active edge depends on the CNTR0 active edge switch bit. Timer X is a 16-bit timer and is equipped with the timer latch. The division ratio of timer X is given by 1/(n+1), where n is the value in the timer latch. Timer X is a down-counter. When the contents of timer X reach “0000 16”, an underflow occurs at the next count pulse and the contents of the timer latch are reloaded into the timer and the count is continued. When the timer underflows, the timer X interrupt request bit is set to “1”. Timer X can be selected in one of four modes by the timer X mode register and can be controlled the timer X write and the real time port. (1) Timer mode The timer counts f(XIN)/16 (or f(XCIN)/16 in low-speed mode). (2) Pulse output mode Each time the timer underflows, a signal output from the CNTR 0 pin is inverted. Except for this, the operation in pulse output mode is the same as in timer mode. When using a timer in this mode, set the P54/CNTR0 pin to output mode (set “1” to bit 4 of port P5 direction register). (3) Event counter mode ●Read and write to timer X high-order, low-order registers When reading and writing to the timer X high-order and low-order registers, be sure to read/write both the timer X high- and low-order registers. When reading the timer X high-order and low-order registers, read the high-order register first. When writing to the timer X high-order and low-order registers, write the low-order register first. The timer X cannot perform the correct operation if the next operation is performed. •Write operation to the high- or low-order register before reading the timer X low-order register •Read operation from the high- or low-order register before writing to the timer X high-order register b7 b0 Timer X mode register (TXM : address 002716) Timer X write control bit 0 : Write value in latch and timer 1 : Write value in latch only Real time port control bit 0 : Real time port function invalid 1 : Real time port function valid RTP0 data for real time port RTP1 data for real time port Timer X operating mode bits b5 b4 0 0 : Timer mode 0 1 : Pulse output mode 1 0 : Event counter mode 1 1 : Pulse width measurement mode CNTR0 active edge switch bit 0 : Count at rising edge in event counter mode Start from “H” output in pulse output mode Measure “H” pulse width in pulse width measurement mode Falling edge active for CNTR0 interrupt 1 : Count at falling edge in event counter mode Start from “L” output in pulse output mode Measure “L” pulse width in pulse width measurement mode Rising edge active for CNTR0 interrupt Timer X stop control bit 0 : Count start 1 : Count stop Fig. 25 Structure of timer X mode register 29 MITSUBISHI MICROCOMPUTERS 7560 Group SINGLE-CHIP 8-BIT CMOS MICROCOMPUTER Timer Y Timer Y is a 16-bit timer and is equipped with the timer latch. The division ratio of timer Y is given by 1/(n+1), where n is the value in the timer latch. Timer Y is a down-counter. When the contents of timer Y reach “000016”, an underflow occurs at the next count pulse and the contents of the timer latch are reloaded into the timer and the count is continued. When the timer underflows, the timer Y interrupt request bit is set to “1”. Timer Y can be selected in one of four modes by the timer Y mode register. (1) Timer mode The timer counts f(XIN)/16 (or f(XCIN)/16 in low-speed mode). (2) Period measurement mode CNTR1 interrupt request is generated at rising or falling edge of CNTR1 pin input signal. Simultaneously, the value in timer Y latch is reloaded in timer Y and timer Y continues counting down. Except for this, the operation in period measurement mode is the same as in timer mode. The timer value just before the reloading at rising or falling of CNTR 1 pin input signal is retained until the next valid edge is input. The rising or falling timing of CNTR 1 pin input signal can be discriminated by CNTR 1 interrupt. When using a timer in this mode, set the P55/CNTR1 pin to input mode (set “0” to bit 5 of port P5 direction register). (3) Event counter mode The timer counts signals input through the CNTR1 pin. Except for this, the operation in event counter mode is the same as in timer mode. When using a timer in this mode, set the P55/CNTR1 pin to input mode (set “0” to bit 5 of port P5 direction register). (4) Pulse width HL continuously measurement mode CNTR 1 interrupt request is generated at both rising and falling edges of CNTR1 pin input signal. Except for this, the operation in pulse width HL continuously measurement mode is the same as in period measurement mode. When using a timer in this mode, set the P5 5 /CNTR 1 pin to input mode (set “0” to bit 5 of port P5 direction register). ■Note on CNTR1 interrupt active edge selection CNTR1 interrupt active edge depends on the value of the CNTR1 active edge switch bit. However, in pulse width HL continuously measurement mode, CNTR1 interrupt request is generated at both rising and falling edges of CNTR 1 pin input signal regardless of the value of CNTR1 active edge switch bit. 30 b7 b0 Timer Y mode register (TYM : address 002816) Not used (“0” at reading) Timer Y operating mode bits b5 b4 0 0 : Timer mode 0 1 : Period measurement mode 1 0 : Event counter mode 1 1 : Pulse width HL continuously measurement mode CNT R1 active edge switch bit 0 : Count at rising edge in event counter mode Measure the falling edge to falling edge period in period measurement mode Falling edge active for CNTR1 interrupt 1 : Count at falling edge in event counter mode Measure the rising edge period in period measurement mode Rising edge active for CNT R1 interrupt Timer Y stop control bit 0 : Count start 1 : Count stop Fig. 26 Structure of timer Y mode register MITSUBISHI MICROCOMPUTERS 7560 Group SINGLE-CHIP 8-BIT CMOS MICROCOMPUTER Timer 1, Timer 2, Timer 3 Timer 1, timer 2, and timer 3 are 8-bit timers and is equipped with the timer latch. The count source for each timer can be selected by the timer 123 mode register. The division ratio of each timer is given by 1/(n+1), where n is the value in the timer latch. All timers are down-counters. When the contents of the timer reach “0016”, an underflow occurs at the next count pulse and the contents of the timer latch are reloaded into the timer and the count is continued. When the timer underflows, the interrupt request bit corresponding to that timer is set to “1”. When a value is written to the timer 1 register and the timer 3 register, a value is simultaneously set as the timer latch and the timer. When the timer 1 register, the timer 2 register, or the timer 3 register is read, the count value of the timer can be read. ●Timer 2 Write Control Which write can be selected by the timer 2 write control bit (bit 2) of the timer 123 mode register (address 002916), writing data to both the latch and the timer at the same time or writing data only to the latch. When the operation “writing data only to the latch” is selected, the value is set to the timer 2 latch by writing data to the timer 2 register and the timer 2 is updated at next underflow. After reset, the operation “writing data to both the latch and the timer at the same time” is selected, and the value is set to both the timer 2 latch and the timer 2 at the same time by writing data to the timer 2 register. If the value is written in latch only, a value is simultaneously set to the timer 2 and the timer 2 latch when the writing in the highorder register and the underflow of timer 2 are performed at the same timing. b7 b0 Timer 123 mode register (T123M :address 002916) TOUT output active edge switch bit 0 : Start at “H” output 1 : Start at “L” output TOUT/φ output enablel bit 0 : TOUT/φ output disabled 1 : TOUT/φ output enabled Timer 2 write control bit 0 : Write data in latch and counter 1 : Write data in latch only Timer 2 count source selection bit 0 : Timer 1 output signal 1 : f(XIN)/16 (or f(XCIN)/16 in low-speed mode) Timer 3 count source selection bit 0 : Timer 1 output signal 1 : f(XIN)/16 (or f(XCIN)/16 in low-speed mode) Timer 1 count source selection bit 0 : f(XIN)/16 (or f(XCIN)/16 in low-speed mode) 1 : f(XCIN) Not used (“0” at reading) Note: System clock φ is f(XCIN)/2 in the low-speed mode. Fig. 27 Structure of timer 123 mode register ●Timer 2 Output Control When the timer 2 (T OUT) output is enabled by the TOUT/φ output enable bit and the TOUT/φ output selection bit, an inversion signal from the TOUT pin is output each time timer 2 underflows. In this case, set the P43/φ/TOUT pin to output mode (set “1” to bit 3 of port P4 direction register). ■Note on Timer 1 to Timer 3 When the count source of timers 1 to 3 is changed, the timer counting value may become arbitrary value because a thin pulse is generated in count input of timer. If timer 1 output is selected as the count source of timer 2 or timer 3, when timer 1 is written, the counting value of timer 2 or timer 3 may become undefined value because a thin pulse is generated in timer 1 output. Therefore, set the value of timer in the order of timer 1, timer 2 and timer 3 after the count source selection of timer 1 to 3. 31 MITSUBISHI MICROCOMPUTERS 7560 Group SINGLE-CHIP 8-BIT CMOS MICROCOMPUTER SERIAL I/O Serial I/O1 ceiver must use the same clock as an operation clock. When an internal clock is selected as an operation clock, transmit or receive is started by a write signal to the transmit buffer register. When an external clock is selected as an operation clock, serial I/ O1 becomes the state where transmit or receive can be performed by a write signal to the transmit buffer register. Transmit and receive are started by input of an external clock. Serial I/O1 can be used as either clock synchronous or asynchronous (UART) serial I/O. A dedicated timer (baud rate generator) is also provided for baud rate generation.

Since the shift register cannot be written to or read from directly, transmit data is written to the transmit buffer, and receive data is read from the receive buffer. The transmit buffer can also hold the next data to be transmitted during transmitting, and the receive buffer register can hold received one-byte data while the next one-byte data is being received.

The transmit buffer register is writeonly and the receive buffer register is read-only. If a character bit length is 7 bits, the MSB of data stored in the receive buffer register is “0”. [Serial I/O1 Status Register (SIO1STS)] 001916 The read-only serial I/O1 status register consists of seven flags (bits 0 to 6) which indicate the operating status of the serial I/O1 function and various errors. Three of the flags (bits 4 to 6) are valid only in UART mode. The receive buffer full flag (bit 1) is set to “0” when the receive buffer register is read. If there is an error, it is detected at the same time that data is transferred from the receive shift register to the receive buffer register, and the receive buffer full flag is set to “1”. A write signal to the serial I/O1 status register sets all the error flags (OE, PE, FE, and SE) (bit 3 to bit 6, respectively) to “0”. Writing “0” to the serial I/O1 enable bit (SIOE) also sets all the status flags to “0”, including the error flags. All bits of the serial I/O1 status register are set to “0” at reset, but if the transmit enable bit of the serial I/O1 control register has been set to “1”, the transmit shift register shift completion flag and the transmit buffer empty flag become “1”. [Serial I/O1 Control Register (SIO1CON)] 001A16 The serial I/O1 control register contains eight control bits for the serial I/O1 function. [UART Control Register (UARTCON)] 001B16 The UART control register consists of the bits which set the data format of an data transmit and receive, and the bit which sets the output structure of the P45/TXD pin. [Baud Rate Generator (BRG)] 001C16 The baud rate generator is the 8-bit counter equipped with a reload register. Set the division value of the BRG count source to the baud rate generator. The baud rate generator divides the frequency of the count source by 1/(n + 1), where n is the value written to the baud rate generator. ■Notes on serial I/O When setting the transmit enable bit to “1”, the serial I/O1 transmit interrupt request bit is automatically set to “1”. When not requiring the interrupt occurrence synchronous with the transmission enabled, take the following sequence. ➀Set the serial I/O1 transmit interrupt enable bit to “0” (disabled). ➁Set the transmit enable bit to “1”. ➂Set the serial I/O1 transmit interrupt request bit to “0” after 1 or more instructions have been executed. ➃Set the serial I/O1 transmit interrupt enable bit to “1” (enabled). 34 MITSUBISHI MICROCOMPUTERS 7560 Group SINGLE-CHIP 8-BIT CMOS MICROCOMPUTER b7 b7 b0 Serial I/O1 status register (SIO1STS : address 001916) b7 b0 Serial I/O1 control register (SIO1CON : address 001A16) Transmit buffer empty flag (TBE) 0: Buffer full 1: Buffer empty BRG count source selection bit (CSS) 0: f(XIN) 1: f(XIN)/4 Receive buffer full flag (RBF) 0: Buffer empty 1: Buffer full Transmit shift register shift completion flag (TSC) 0: Transmit shift in progress 1: Transmit shift completed Serial I/O1 synchronous clock selection bit (SCS) 0: BRG output divided by 4 when clock synchronous serial I/O is selected.

For serial I/O2, the transmitter and the receiver must use the same clock as a synchronous clock. When an internal clock is selected as a synchronous clock, the serial I/O2 is initialized and, transmit and receive is started by a write signal to the serial I/O2 register. When an external clock is selected as an synchronous clock, the serial I/O2 counter is initialized by a write signal to the serial I/O2 register, serial I/O2 becomes the state where transmission or reception can be performed. Write to the serial I/O2 register while SCLK21 is “H” state when an external clock is selected as an synchronous clock. Either P62/SCLK21 or P63/SCLK22 pin can be selected as an output pin of the synchronous clock.

After writing, whenever a synchronous clock changes from “H” to “L”, data is output from the SOUT2 pin. Moreover, whenever a synchronous clock changes from “L” to “H”, data is taken in from the SIN2 pin, and 1 bit shift of the serial I/O2 register is carried out simultaneously. When the internal clock is selected as a synchronous clock, it is as follows if a synchronous clock is counted 8 times. •Serial I/O2 counter = “0” •Synchronous clock stops in “H” state •Serial I/O2 interrupt request bit = “1” The SOUT2 pin is in a high impedance state after transfer is completed. When the external clock is selected as a synchronous clock, if a synchronous clock is counted 8 times, the serial I/O2 interrupt request bit is set to “1”, and the SOUT2 pin holds the output level of D7. However, if a synchronous clock continues being input, the shift of the serial I/O2 register is continued and transmission data continues being output from the SOUT2 pin.

However, if synchronous clocks input are carried on, the transmit data will be output continuously from the SOUT2 pin because shifts of serial I/O2 shift register is continued as long as synchronous clocks are input. Fig. 35 Timing of serial I/O2 function 37 MITSUBISHI MICROCOMPUTERS 7560 Group SINGLE-CHIP 8-BIT CMOS MICROCOMPUTER PULSE WIDTH MODULATION (PWM) PWM Operation The 7560 group has a PWM function with an 8-bit resolution, using f(XIN) or f(XIN)/2 as a count source. When either bit 1 (PWM0 function enable bit) or bit 2 (PWM1 function enable bit) of the PWM control register or both bits are enabled, operation starts from initializing status, and pulses are output starting at “H”. When one PWM output is enabled and that the other PWM output is enabled, PWM output which is enabled to output later starts pulse output from halfway of PWM period (see Figure 39). When the PWM register or PWM prescaler is updated during PWM output, the pulses will change in the cycle after the one in which the change was made. Data Setting The PWM output pins are shared with ports P50 and P51. Set the PWM period by the PWM prescaler, and set the period during which the output pulse is an “H” by the PWM register. If PWM count source is f(XIN) and the value in the PWM prescaler is n and the value in the PWM register is m (where n = 0 to 255 and m = 0 to 255) : PWM period = 255 ✕ (n+1)/f(XIN) = 31.875 ✕ (n+1) µs (when f(XIN) = 8 MHz) Output pulse “H” period = PWM period ✕ m/255 = 0.125 ✕ (n+1) ✕ m µs (when f(XIN) = 8 MHz) 31.875 ✕ m ✕ (n+1) µs 255 PWM output T = [31.875 ✕ (n+1)] µs m: Contents of PWM register n : Contents of PWM prescaler T : PWM cycle (when f(X IN ) = 8 MHz) Fig. 36 Timing of PWM cycle Data bus PWM prescaler pre-latch PWM register pre-latch PWM1 function enable bit Transfer control circuit PWM prescaler latch PWM register latch Port P51 lacth P51 /PWM1 Count source selection bit “0” PWM prescaler XIN 1/2 PWM circuit P50 /PWM0 “1” Port P50 lacth PWM0 function enable bit Fig. 37 Block diagram of PWM function 38 MITSUBISHI MICROCOMPUTERS 7560 Group SINGLE-CHIP 8-BIT CMOS MICROCOMPUTER b0 b7 PWM control register (PWMCON : address 002B16) Count source selection bit 0 : f(XIN) 1 : f(XIN)/2 PWM0 function enable bit 0 : PWM0 disabled 1 : PWM0 enabled PWM1 function enable bit 0 : PWM1 disabled 1 : PWM1 enabled Not used (“0” at reading) Fig. 38 Structure of PWM control register A PWM (internal) C B B = C T2 T stop stop T T T2 Port PWM 0 output PWM 1 output Port Port Port PWM register write signal (Changes from “A” to “B” during “H” period) PWM prescaler write signal (Changes from “T” to “T2” during PWM period) PWM 0 function enable bit PWM 1 function enable bit When the contents of the PWM register or PWM prescaler have changed, the PWM output will change from the next period after the change.

When reading this register during an A-D conversion, the previous conversion result is read. The high-order 8 bits of a conversion result is stored in the A-D conversion high-order register (address 003516), and the low-order 2 bits of the same result are stored in bit 7 and bit 6 of the A-D conversion low-order register (address 001416). Bit 0 of the A-D conversion low-order register is the conversion mode selection bit. When this bit is set to “0”, that becomes the 10-bit A-D mode. When this bit is set to “1”, that becomes the 8-bit A-D mode. Comparator and Control Circuit The comparator and control circuit compare an analog input voltage with the comparison voltage and store the result in the A-D conversion register. When an A-D conversion is completed, the control circuit sets the AD conversion completion bit and the AD converter interrupt request bit to “1”. Note that because the comparator consists of a capacitor coupling, set f(XIN) to 500 kHz or more during an A-D conversion. Use the clock divided from the main clock f(XIN) as the system clock φ. b7 b0 Analog input pin selection bits b2b1b0 0 0 0 0 1 1 1 1 [A-D Control Register (ADCON)] 003416 The A-D control register controls the A-D conversion process. Bits 0 to 2 of this register select specific analog input pins. Bit 3 indicates the completion of an A-D conversion. The value of this bit remains at “0” during an A-D conversion, then it is set to “1” when the A-D conversion is completed. Writing “0” to this bit starts the A-D conversion. Bit 4 is the VREF input switch bit which controls connection of the resistor ladder and the reference voltage input pin (V REF). The resistor ladder is always connected to V REF when bit 4 is set to “1”. When bit 4 is set to “0”, the resistor ladder is cut off from VREF except for A-D conversion performed. When bit 5, which is the AD external trigger valid bit, is set to “1”, A-D conversion starts also by a falling edge of an ADT input. When using an A-D external trigger, set the P57/ADT pin to input mode (set “0” to bit 7 of port P5 direction register). Comparison Voltage Generator The comparison voltage generator divides the voltage between AVSS and VREF by 256 (when 8-bit A-D mode) or 1024 (when 10bit A-D mode), and outputs the divided voltages.

The D-A converter is started by setting the value in the D-A conversion register. When the DA1 output enable bit or the DA2 output enable bit is set to “1”, the result of D-A conversion is output from the corresponding DA pin. When using the D-A converter, set the P56/DA1 pin and the P57/DA2 pin to input mode (set “0” to bits 6, 7 of port P5 direction register) and the pull-up resistor should be in the OFF state (set “0” to bit 3 of PULL register B) previously. The output analog voltage V is determined by the value n (base 10) in the D-A conversion register as follows: b7 b0 0 0 0 0 0 0 D-A control register (DACON : address 003616) DA1 output enable bit 0 : Disabled 1 : Enabled DA2 output enable bit 0 : Disabled 1 : Enabled Not used (“0” at reading) (Write “0” to these bits at writing.) V=VREF ✕ n/256 (n=0 to 255) Where VREF is the reference voltage. Fig. 43 Structure of D-A control register At reset, the D-A conversion registers are set to “0016”, the DA1 output enable bit and the DA2 output enable bit are set to “0”, and the P5 6/DA 1 pin and the P57 /DA 2 pin goes to high impedance state. The DA converter is not buffered, so connect an external buffer when driving a low-impedance load. ■ Note on applied voltage to VREF pin When these pins are used as D-A conversion output pins, the Vcc level is recommended for the applied voltage to VREF pin. When the voltage below Vcc level is applied, the D-A conversion accuracy may be worse.

This circuit inputs a reference voltage for boosting from LCD power input pin VL1. Set each bit of the segment output enable register and the LCD mode register in the following order for operating the voltage multiplier. 1. Set the segment output enable bits (bits 0 to 5) of the segment output enable register to “0” or “1”. 2. Set the duty ratio selection bits (bits 0 and 1), the bias control bit (bit 2), the LCD circuit divider division ratio selection bits (bits 5 and 6), and the LCDCK count source selection bit (bit 7) of the LCD mode register to “0” or “1”. 3. Set the LCD output enable bit (bit 6) of the segment output enable register to “1”. Apply the limit voltage or less to the VL1 pin. 4. Set the voltage multiplier control bit (bit 4) of the LCD mode register to “1”. However, be sure to select 1/3 bias for bias control. When voltage is input to the VL1 pin during operating the voltage multiplier, voltage that is twice as large as VL1 occurs at the VL2 pin, and voltage that is three times as large as VL1 occurs at the VL3 pin. Bias Control and Applied Voltage to LCD Power Input Pins To the LCD power input pins (VL1–V L3), apply the voltage shown in Table 12 according to the bias value. Select a bias value by the bias control bit (bit 2 of the LCD mode register). Table 12 Bias control and applied voltage to VL1–VL3 Bias value 1/3 bias 1/2 bias Voltage value VL3=VLCD VL2=2/3 VLCD VL1=1/3 VLCD VL3=VLCD VL2=VL1=1/2 VLCD Note : V LCD is the maximum value of supplied voltage for the LCD panel. ■Notes on Voltage Multiplier When using the voltage multiplier, apply the limit voltage or less to the V L1 pin, then set the voltage multiplier control bit to “1” (enabled). When not using the voltage multiplier, set the LCD output enable bit to “1”, then apply proper voltage to the LCD power input pins (VL1–VL3). When the LCD output enable bit is set to “0” (disabled), the V CC voltage is applied to the VL3 pin inside of this microcomputer.

Select duty ratio by the duty ratio selection bits (bits 0 and 1 of the LCD mode register). After reset, the VCC (VL3) voltage is output from the common pins. Addresses 004016 to 005316 are the designated RAM for the LCD display. When “1” are written to these addresses, the corresponding segments of the LCD display panel are turned on.

Segment signals are output according to the bit data of the LCD RAM corresponding to the duty ratio. After reset, a VCC (=VL3 ) voltage is output to the segment-only pins and the segment/output port pins are the high impedance condition and pulled up to VCC (=VL3) voltage. Also, the segment/I/O port pins(SEG26–SEG39) are set to input mode as I/O ports, and VCC (=VL3) is applied to them by pull-up resistor.

Watchdog Timer The watchdog timer gives a mean of returning to the reset status when a program cannot run on a normal loop (for example, because of a software runaway). The watchdog timer consists of an 8-bit watchdog timer L and a 6bit watchdog timer H. At reset or writing to the watchdog timer control register (address 0037 16), the watchdog timer is set to “3FFF16”. When any data is not written to the watchdog timer control register (address 0037 16) after reset, the watchdog timer is stopped. The watchdog timer starts to count down from “3FFF16” by writing to the watchdog timer control register and an internal reset occurs at an underflow. Accordingly, when using the watchdog timer function, write the watchdog timer control register before an underflow. The watchdog timer does not function when writing to the watchdog timer control register has not been done after reset. When not using the watchdog timer, do not write to it. When the watchdog timer control register is read, the following values are read: Data bus “FF16” is set when watchdog timer is written to. XCIN “1” Internal system clock selection bit (Note) “0” 1/16 When the STP instruction disable bit is “0”, the STP instruction is enabled. The STP instruction is disabled when this bit is set to “1”. If the STP instruction which is disabled is executed, it is processed as an undefined instruction, so that a reset occurs internally. This bit can be set to “1” but cannot be set to “0” by program. This bit is “0” after reset. When the watchdog timer H count source selection bit is “0”, the detection time is set to 8.19 s at f(XCIN) = 32 kHz and 32.768 ms at f(XIN) = 8 MHz. When the watchdog timer H count source selection bit is “0”, the detection time is set to 32 ms at f(XCIN) = 32 kHz and 128 µs at f(XIN) = 8 MHz. There is no difference in the detection time between the middle-speed mode and the high-speed mode.

An oscillation circuit can be formed by connecting an oscillator between X IN and X OUT (X CIN and X COUT). Use the circuit constants in accordance with the oscillator manufacturer’s recommended values. No external resistor is needed between X IN and XOUT since a feed-back resistor exists on-chip. However, an external feed-back resistor is needed between XCIN and XCOUT since a resistor does not exist between them. To supply a clock signal externally, input it to the XIN pin and make the XOUT pin open. The sub-clock oscillation circuit cannot directly input clocks that are externally generated. Accordingly, be sure to cause an external oscillator to oscillate. Immediately after poweron, only the XIN oscillation circuit starts oscillating, and XCIN and XCOUT pins go to high-impedance state. Frequency Control (1) Middle-speed mode The clock input to the XIN pin is divided by 8 and it is used as the system clock φ. After reset, this mode is selected. (2) High-speed mode The clock input to the XIN pin is divided by 2 and it is used as the system clock φ. Oscillation Control (1) Stop mode If the STP instruction is executed, the system clock φ stops at an “H” level, and main and sub clock oscillators stop. In this time, values set previously to timer 1 latch and timer 2 latch are loaded automatically to timer 1 and timer 2. Before the STP instruction, set the values to generate the wait time required for oscillation stabilization to timer 1 latch and timer 2 latch (low-order 8 bits are set to timer 1, high-order 8 bits are set to timer 2). Either f(XIN) or f(XCIN) divided by 16 is input to timer 1 as count source, and the output of timer 1 is connected to timer 2. The bits of the timer 123 mode register except bit 4 are set to “0”. Set the timer 1 and timer 2 interrupt enable bits to “0” before executing the STP instruction. Oscillation restarts at reset or when an external interrupt is received, but the system clock φ is not supplied to the CPU until timer 2 underflows. This allows time for the clock circuit oscillation to stabilize when a ceramic resonator is used. (2) Wait mode If the WIT instruction is executed, only the system clock φ stops at an “H” state. The states of main clock and sub clock are the same as the state before the executing the WIT instruction, and oscillation does not stop. Since supply of internal clock φ is started immediately after the interrupt is received, the instruction can be executed immediately. (3) Low-speed mode • The clock input to the XCIN pin is divided by 2 and it is used as the system clock φ. •A low-power consumption operation can be realized by stopping the main clock in this mode. To stop the main clock, set the main clock stop bit of the CPU mode register to “1”. When the main clock is restarted, after setting the main clock stop bit to “0”, set enough time for oscillation to stabilize by program. Note: If you switch the mode between middle/high-speed and lowspeed, stabilize both X IN and X CIN oscillations. The sufficient time is required for the sub clock to stabilize, especially immediately after poweron and at returning from stop mode. When switching the mode between middle/highspeed and low-speed, set the frequency in the condition that f(XIN) > 3•f(XCIN).

Fig. 62 State transitions of system clock 56 MITSUBISHI MICROCOMPUTERS 7560 Group SINGLE-CHIP 8-BIT CMOS MICROCOMPUTER NOTES ON PROGRAMMING Processor Status Register The contents of the processor status register (PS) after a reset are undefined, except for the interrupt disable flag (I) which is “1”. After a reset, initialize flags (T flag, D flag, etc.) which affect program execution. Interrupt When the contents of an interrupt request bits are changed by the program, execute a BBC or BBS instruction after at least one instruction. This is for preventing executing a BBC or BBS instruction to the contents before change. Serial I/O In clock synchronous serial I/O, if the receive side is using an external clock and it is to output the SRDY signal, set the transmit enable bit, the receive enable bit, and the SRDY output enable bit to “1”. The TxD pin of serial I/O1 retains the level then after transmission is completed. In serial I/O2 selecting an internal clock, the SOUT2 pin goes to high impedance state after transmission is completed. In serial I/O2 selecting an external clock, the SOUT2 pin retains the level then after transmission is completed. A-D Converter Decimal Calculations To calculate in decimal notation, set the decimal mode flag (D) to “1”, then execute an ADC or SBC instruction. After executing an ADC or SBC instruction, execute at least one instruction before executing a SEC, CLC, or CLD instruction. In decimal mode, the values of the negative (N), overflow (V), and zero (Z) flags are invalid. Multiplication and Division Instructions The index mode (T) and the decimal mode (D) flags do not affect the MUL and DIV instruction. The execution of these instructions does not change the contents of the processor status register. The input to the comparator is combined by internal capacitors. Therefore, since conversion accuracy may be worse by losing of an electric charge when the conversion speed is not enough, make sure that f(XIN) is at least 500 kHz during an A-D conversion. The normal operation of A-D conversion cannot be guaranteed when performing the next operation: •When writing to CPU mode register during A-D conversion operation •When writing to A-D control register during A-D conversion operation •When executing STP instruction or WIT instruction during A-D conversion operation Instruction Execution Time Ports Use instructions such as LDM and STA, etc., to set the port direction registers. The contents of the port direction registers cannot be read. The following cannot be used: • LDA instruction • The memory operation instruction when the T flag is “1” • The bit-test instruction (BBC or BBS, etc.) • The read-modify-write instruction (calculation instruction such as ROR etc., bit manipulation instruction such as CLB or SEB etc.) • The addressing mode which uses the value of a direction register as an index The instruction execution time is obtained by multiplying the frequency of the system clock φ by the number of cycles needed to execute an instruction. The number of cycles required to execute an instruction is shown in the list of machine instructions. The frequency of the system clock φ depends on the main clock division ratio selection bit and the system clock selection bit. 57 MITSUBISHI MICROCOMPUTERS 7560 Group SINGLE-CHIP 8-BIT CMOS MICROCOMPUTER NOTES ON USE Countermeasures Against Noise Noise (1) Shortest wiring length ➀ Wiring for RESET pin Make the length of wiring which is connected to the RESET pin as short as possible. Especially, connect a capacitor across the RESET pin and the VSS pin with the shortest possible wiring (within 20 mm). ● Reason The width of a pulse input into the RESET pin is determined by the timing necessary conditions. If noise having a shorter pulse width than the standard is input to the RESET pin, the reset is released before the internal state of the microcomputer is completely initialized. This may cause a program runaway. Noise Reset circuit RESET VSS VSS N.G. Reset circuit VSS RESET VSS O.K. Fig. 63 Wiring for the RESET pin ➁ Wiring for clock input/output pins • Make the length of wiring which is connected to clock I/O pins as short as possible. • Make the length of wiring (within 20 mm) across the grounding lead of a capacitor which is connected to an oscillator and the VSS pin of a microcomputer as short as possible. • Separate the V SS pattern only for oscillation from other V SS patterns. ● Reason If noise enters clock I/O pins, clock waveforms may be deformed. This may cause a program failure or program runaway. Also, if a potential difference is caused by the noise between the VSS level of a microcomputer and the VSS level of an oscillator, the correct clock will not be input in the microcomputer. 58 XIN XOUT VSS N.G.

Be careful especially when range of voltage or/and temperature is wide. Also, take care to prevent an oscillator that generates clocks for a microcomputer operation from being affected by other signals. ➀ Keeping oscillator away from large current signal lines Install a microcomputer (and especially an oscillator) as far as possible from signal lines where a current larger than the tolerance of current value flows. ● Reason In the system using a microcomputer, there are signal lines for controlling motors, LEDs, and thermal heads or others. When a large current flows through those signal lines, strong noise occurs because of mutual inductance. ➁ Installing oscillator away from signal lines where potential levels change frequently Install an oscillator and a connecting pattern of an oscillator away from signal lines where potential levels change frequently. Also, do not cross such signal lines over the clock lines or the signal lines which are sensitive to noise. ● Reason Signal lines where potential levels change frequently (such as the CNTR pin signal line) may affect other lines at signal rising edge or falling edge. If such lines cross over a clock line, clock waveforms may be deformed, which causes a microcomputer failure or a program runaway. ➀ Keeping oscillator away from large current signal lines (4) Analog input The analog input pin is connected to the capacitor of a comparator. Accordingly, sufficient accuracy may not be obtained by the charge/discharge current at the time of A-D conversion when the analog signal source of high-impedance is connected to an analog input pin. In order to obtain the A-D conversion result stabilized more, please lower the impedance of an analog signal source, or add the smoothing capacitor to an analog input pin. (5) Difference of memory type and size When Mask ROM and PROM version and memory size differ in one group, actual values such as an electrical characteristics, A-D conversion accuracy, and the amount of proof of noise incorrect operation may differ from the ideal values. When these products are used switching, perform system evaluation for each product of every after confirming product specification. (6) Wiring to VPP pin of One Time PROM version and EPROM version Connect an approximately 5 kΩ resistor to the VPP pin the shortest possible in series. Note: Even when a circuit which included an approximately 5 kΩ resistor is used in the Mask ROM version, the microcomputer operates correctly. ● Reason The VPP pin of the PROM version is the power source input pin for the built-in PROM. When programming in the built-in PROM, the impedance of the VPP pin is low to allow the electric current for writing flow into the built-in PROM. Because of this, noise can enter easily. If noise enters the VPP pin, abnormal instruction codes or data are read from the built-in PROM, which may cause a program runaway.
