• P20 is also used as the serial input SI0

I/O

pin.

• P21 is also used as the serial output

SO0 pin.

• P22 is also used as the serial clock

SCK0 pin.

P30/INT1

P31/POUT0

P32/POUT1

I/O

• P30 is also used as the INT1 interrupt

request.

• P31 is also used for the square wave

output from timer 0.

• P32 is also used for the square wave

and PWM output from timer 1.

• Pch: CMOS type

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.

P40/INV0I

P41/INV0O

P42/INV1I

P43/INV1O

I/O ports P40 to P43

I/O

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

• Input or output in 8-bit units when used

in conjunction with P50 to P53.

• Can be used for output of 8-bit ROM

data when used in conjunction with

P50 to P53.

• Pch: Pull-up MOS type
