PORTC is an 8-bit bidirectional port. PORTC is
multiplexed with several peripheral functions. PORTC
pins have Schmitt Trigger input buffers.
All PORTC pins have latch bits (PORTC register).
They will modify the contents of the PORTC latch
(when written); thus, modifying the value driven out on
a pin if the corresponding TRISC bit is configured for
output.
