P0 Port
9.3.1
P0 Port Description
P0 is 8-bit I/O port. P0 control registers consist of P0 data register (P0), P0 direction register (P0IO), debounce
enable register (P0DB), P0 pull-up resistor selection register (P0PU) and P0 open-drain selection register (P0OD).
Refer to the port function selection registers for the P0 function selection.
