9.9 P6 Port
9.9.1 P6 Port Description
P6 is 6-bit I/O port. P6 control registers consist of P6 data register (P6), P6 direction register (P6IO), P6 pull-up resistor
selection register (P6PU) and P6 open-drain selection register (P6OD) . Refer to the port function selection registers
for the P6 function selection.
