M16C / 62M (80-pin version) Group (Low voltage version) SINGLE-CHIP 16-BIT CMOS MICROCOMPUTER About the M16C/62M (80-pin version) group (low voltage version) The M16C/62M (80-pin version) group (low voltage version) is packaged in a 80-pin plastic mold package. The number of pins in comparison with the 100-pin package products is decreased. So be careful about the following. (a) The M16C/62M (80-pin version) group (low voltage version) supports single chip mode alone. It supports neither memory expansion mode nor microprocessor mode. (b) The input/output ports given below are absent from the M16C/62M (80-pin version) group (low voltage version). To stabilize the internal state, set to output mode the direction register of each input/output port. Failing in setting to output mode involves an increase in current consumption. P10 to P17, P44 to P47, P72 to P75, P91 (c) INT3 to INT5 allocated to P15 to P17 cannot be used. Keep the INT3 interrupt control register disabled for interrupts. The INT4 interrupt control register and the INT5 interrupt control register are shared with SI/O3 and SI/O4. When the user don’t use them as SI/O3 and SI/4, set them disabled for interrupts. (d) The output pins of timers A1 and A2 - TA1IN, TA1OUT, TA2IN and TA2OUT - allocated to P72 to P75 cannot be used. In connection with this, the gate function and pulse outputting function of timers A1 and A2 cannot be used. Use timer mode and internal event count, or use as trigger signal generation in one-shot timer mode. ______ ______ (e) The UART2 input/output pins - CLK2 and CTS/RTS - allocated to P72 and P73 cannot be used. In connection with this, UART2 solely as UART of the internal clock can be used. (f) The input pin TB1IN of timer B1 allocated to P91 cannot be used. With timer B1 under this state, use only timer mode or the internal event count. (g) The input pin SIN3 of serial I/O3 allocated to P91 cannot be used. In connection with this, use serial I/O3 as a serial I/O exclusive to transmission. (h) The output pins for three-phase motor control allocated to P72 to P75 cannot be used. So set to 0 (ordinary mode) the mode select bit (bit 2) of three-phase PWM control register 0. 7 Mitsubishi microcomputers . Electrical characteristics (Vcc = 3V) Table 1.20.1.

Usage precaution Usage Precaution Timer A (timer mode) M16C / 62M (80-pin version) Group (Low voltage version) SINGLE-CHIP 16-BIT CMOS MICROCOMPUTER (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. 16 Mitsubishi microcomputers . Usage precaution M16C / 62M (80-pin version) Group (Low voltage version) 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. 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 AD 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”. 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”. 17 Mitsubishi microcomputers . Usage precaution M16C / 62M (80-pin version) Group (Low voltage version) SINGLE-CHIP 16-BIT CMOS MICROCOMPUTER (4) External interrupt _______ ________ • When the polarity of the INT0 to INT2 pins is changed, the interrupt request bit is sometimes set to "1". After changing the polarity, set the interrupt request bit to "0". (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 I ; Enable interrupts. Example 2: INT_SWITCH2: FCLR I AND.B #00h, 0055h MOV.W MEM, R0 FSET I ; Disable interrupts. ; Clear TA0IC int. priority level and int. request bit. ; Dummy read. ; Enable interrupts. Example 3: INT_SWITCH3: PUSHC FLG FCLR I AND.B #00h, 0055h POPC FLG ; Push Flag register onto stack ; Disable interrupts. ; Clear TA0IC int. priority level and int. request bit. ; Enable interrupts. The reason why two NOP instructions or dummy read are inserted before FSET I in Examples 1 and 2 is to prevent the interrupt enable flag I from being set before the interrupt control register is rewritten due to effects of the instruction queue. • 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 instructions to change the register. Instructions : AND, OR, BCLR, BSET Noise (1) Insert bypass capacitor between VCC and VSS pin for noise and latch up countermeasure. • Insert bypass capacitor (about 0.1 µF) and connect short and wide line between VCC and VSS lines. 18 Mitsubishi microcomputers M16C / 62M (80-pin version) Group (Low voltage version) SINGLE-CHIP 16-BIT CMOS MICROCOMPUTER GZZ-SH13-96B Mask ROM number Date : Note : Please complete all items marked g . ) Receipt MITSUBISHI ELECTRIC-CHIP 16-BIT MICROCOMPUTER M30621MCM-XXXGP MASK ROM CONFIRMATION FORM Section head signature Supervisor signature g Customer Date issued g1.
