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 single-bit units.)
• Used as data pins in EPROM mode
I/O ports P10 to P13
• Input or output in 4-bit or 1-bit units
• Used as data pins in EPROM mode
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.
• Used as address pins in EPROM mode
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.
• Used as address pins in EPROM mode
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.
• Dedicated inverter circuit (option)
• Used as address pins in EPROM mode
