M16C / 62M (80-pin version) Group

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 pack-
age. 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.

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.

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 genera-
tion in one-shot timer mode.
(e) The UART2 input/output pins - CLK2 and CTS/RTS - allocated to P7
2
and P7
3
cannot be used. In
connection with this, UART2 solely as UART of the internal clock can be used.
(f) The input pin TB1
IN
of timer B1 allocated to P9
1
cannot be used. With timer B1 under this state, use
only timer mode or the internal event count.
(g) The input pin S
IN3
of serial I/O3 allocated to P9
1
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 P7
2
to P7
5
cannot be used. So set to 0
(ordinary mode) the mode select bit (bit 2) of three-phase PWM control register 0.
