This pin is used for GPIO. It is
individually programmed as input or
output and is also used individually as
an interrupt input. Each Port C pin,
when programmed as output is
selected to be an open-drain or open-
source output. Port C is multiplexed
with one UART.
Modem control signal from UART.
This signal is multiplexed with PC2.
