Pin Description
I/O Bit-programmable I/O port for Schmitt trigger input or
push-pull output. Pull-up resistors are assignable by
software. Port0 pins can also be used as A/D converter
input, PWM output or external interrupt input.
I/O Bit-programmable I/O port for Schmitt trigger input or
push-pull, open-drain output. Pull-up resistors or pull-down
resistors are assignable by software.
I Schmitt trigger input port
I/O Bit-programmable I/O port for Schmitt trigger input or
push-pull, open-drain output. Pull-up resistors are
assignable by software.
