I/O ports P20 to P23

• Input or output in 4-bit or 1-bit units

• P20 is also used as the serial input SI0

pin.

• P21 is also used as the serial output

request pin, and also as the timer 0

event counting and pulse width

measurement input.

I/O ports P30 to P32

P30/INT1

P31/POUT0

P32/POUT1

• Input or output in 3-bit or 1-bit units

• P30 is also used as the INT1 interrupt

I/O

request.

• P31 is also used for the square wave

output from timer 0.

• P32 is also used for the square wave

• Pch: CMOS type

• Nch: Intermediate sink current

type

• Nch: +15-V handling when OD

option selected

CMOS or Nch OD

output

H

output from timer 1.

P33/HOLD

Hold mode control input

• Hold mode is set up by the HOLD

instruction when HOLD is low.

• In hold mode, the CPU is restarted by

setting HOLD to the high level.

I

• This pin can be used as input port P33

along with P30 to P32.

• When the P33/HOLD pin is at the low

level, the CPU will not be reset by a low

level on the RES pin. Therefore,

applications must not set P33/HOLD low

when power is first applied.
