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.
