Description
I/O port with bit programmable pins;
Schmitt trigger input or output mode
selected by software; software assignable
pull-up. P0.0–P0.7 can be used as inputs
for external interrupts INT0–INT7
(with noise filter and interrupt control).
I/O port with bit programmable pins; Input
or output mode selected by software;
Open-drain output mode can be selected
by software; software assignable pull-up.
Alternately P1.0–P1.7 can be used as SI,
SO, SCK, BUZ, T1CAP, T1CLK, T1OUT,
T1PWM
I/O port with bit programmable pins;
normal input and AD input or output
mode selected by software; software
assignable pull-up.
I/O port with bit programmable pins. Input
or push-pull output with software
assignable pull-up. Alternately P3.0–P3.3
can be used as TACAP, TACLK, TAOUT,
TAPWM, TBPWM
I/O port with bit programmable pins.
Push-pull or open drain output and input
with software assignable pull-up.
P4.0–P4.7 can alternately be used as
outputs for LCD SEG
Have the same characteristic as port 4
