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

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.
