Description
This pin can be used for general-purpose I/
O. It can be individually programmed as
input or output and can also be used
individually as an interrupt input. Each Port
C pin, when programmed as output, can be
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.
