10.1 Overview
Parallel Port C is a byte-wide port with each bit programmable for data direction and drive
level. These are simple inputs and outputs controlled and reported in the Port C Data Reg-
ister (PCDR).
All the Parallel Port C pins have alternate output functions, and most of them can be used
as inputs to various on-chip peripherals.
