This pin is the input to the onboard
crystal oscillator for the primary
system clock. If an external
oscillator is used, its clock output
must be connected to this pin. When
a crystal is used, it must be
connected between X

Ground.
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.
This pin is used by the UART to
transmit asynchronous serial data.
This signal is multiplexed with PC0.
