P0.0–P0.7
I/O
Bit programmable port; input or output mode
selected by software; normal input or push-pull
output with software assignable pull-up (P0.0–P0.3)
or pull-down (P0.4–P0.7). Alternately, P0.4–P0.7 can
be use as a ADC input port with
8-bit resolution.

P1.0–P1.7
I/O
Bit programmable port; input or output mode
selected by software; normal input or push-pull
output with software assignable pull-up. P1.5–P1.7
can be used as a synchronous SIO port

P2.0–P2.7
I/O
General I/O port with normal input or push-pull output
with software; assignable pull-up. Bit programmable.
Alternately, P2.0–P2.7 can be used as inputs for
external interrupts, INT0–INT7 (with noise filter and
interrupt control). INT0/INT1 is level interrupts.

P3.0–P3.7
I/O
General I/O port with bit programmable pins.
Normal input or push-pull output with software
assignable pull-up. Input or output mode is selectable
by software. Respectively, each pin can serve as
(with noise filters):
P3.0/timer D clock input (TDCK)
P3.1/timer C clock input (TCCK)
P3.2/timer D capture input (TDCAP)
P3.3/timer C capture input (TCCAP)
P3.4/timer C out (TCOUT)/PWM out (TCPWM)
P3.5/timer D out (TDOUT)/PWM out (TDPWM)
P3.6/PWM0 output port
P3.7/PWM1 output port

P4.0–P4.7
I/O
General I/O port with bit programmable pins.
Normal input or push-pull output with software
assignable pull-up. Input or output mode is selectable
by software. P4.0–P4.7 can alternately be used as
inputs for embedded chip selection output.
