P1 Port
9.4.1
P1 Port Description
P1 is 8-bit I/O port. P1 control registers consist of P1 data register (P1), P1 direction register (P1IO), debounce enable
register (P1DB), P1 pull-up resistor selection register (P1PU) and P1 open-drain selection register (P1OD) . Refer to
the port function selection registers for the P1 function selection.
