pin.

• P21 is also used as the serial output

SO0 pin.

• P22 is also used as the serial clock

SCK0 pin.

• P23 is also used as the INT0 interrupt

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

I/O

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

• P30 is also used as the INT1 interrupt

request.

• P31 is also used for the square wave

output from timer 0.

• P31 and P32 also support 3-state

• Pch: CMOS type

• Nch: Intermediate sink current

type

• Nch: +15V handling when OD

option selected

CMOS or Nch OD

output

H

outputs.

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.

I/O ports P40 to P43
