I/O ports P00 to P03
Input or output in 4-bit or 1-bit units
P00 to P03 support the halt mode
control function (This function can be
specified in bit units.)
I/O ports P10 to P13
Input or output in 4-bit or 1-bit units
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 pin, and also as the timer 0
event counting and pulse width
measurement input.
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 the square wave
output from timer 0.
P32 is also used for the square wave
and PWM output from timer 1.
P31 and P32 also support 3-state
outputs.
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.
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
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.
