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.

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.

connection with this, UART2 solely as UART of the internal clock can be used.

only timer mode or the internal event count.

I/O3 as a serial I/O exclusive to transmission.
