Description
Bit programmable port; input or output mode
selected by software; input or push-pull output.
Software assignable pull-up.
P4.0-P4.7 can alternately be used as inputs for
external interrupts INT0-INT7, respectively (with
noise filters and interrupt controller)
Bit programmable port; input or output mode
selected by software; input or push-pull output.
Software assignable pull-up.
Alternately, P5.0~P5.3 can be used as I/O for serial
por, UART0, UART1, respectively.
N-channel, open-drain output only port.
General-purpose digital input ports. Alternatively
used as analog input pins for A/D converter
modules.
Bit programmable port; input or output mode
selected by software; input or push-pull output.
Software assignable pull-up.
P8.4, P8.5 can alternately be used as inputs for
external interrupts INT8, INT9, respectively (with
noise filters and interrupt controller)
