P4 Port
9.7.1
P4 Port Description
P4 is 4-bit I/O port. P4 control registers consist of P4 data register (P4), P4 direction register (P4IO), P4 pull-up resistor
selection register (P4PU) and P4 open-drain selection register (P4OD).Refer to the port function selection registers for
the P4 function selection.
