Write:
This bit enables the PC1 contact sense circuitry.
This bit enables the PC0 contact sense circuitry.
This flag indicates that a contact sense transition has occurred and an
interrupt request is pending. The flag can be cleared by writing a 1 to
it.
This flag indicates a short circuit on PC6 is active and an interrupt
request is pending.
