I/O ports P10 to P13

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

type

• N-channel: intermediate

sink current type

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

SO0 pin.

• P22 is also used as the serial clock

SCK0 pin.

• P23 is also used as the INT0

interrupt request, the timer 0 event

counter and pulse width

measurement input.

• P-channel: CMOS type

• N-channel: intermediate

sink current type (+15 V

withstand voltage in OD)

I/O ports P30 to P32

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

• P30 is also used as the INT1

interrupt request.

• P31 is also used for square wave

output from timer 0.

• P32 is also used for square wave

output from timer 1 and PWM

output.

• P-channel: CMOS type

• N-channel: intermediate

sink current type (+15 V

withstand voltage in OD)

• Either with pull-up MOS

or n-channel OD output

• Reset output level

High or low level (option)

• Either CMOS or n-channel

OD output

H

• Either CMOS or n-channel

OD output

H

Hold mode control input

• Hold mode is entered if a HOLD

instruction is executed when HOLD

is low.

• When in hold mode, the CPU is

reactivated by setting HOLD to the

high level.

P33/HOLD

I

• P33 can also be used as an input

port along with P30 to P32.

• When P33/HOLD is low, the CPU

will not be reset by a low level on

RES. Therefore, RES cannot be

used in applications that set

P33/HOLD low when power is first

applied.

I/O ports P40 to P43
