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 status signal to the UART. This
signal is multiplexed with PC6.

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