CSIF – Port C Contact Sense Interrupt Flag
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.
1 = Flag set when a transition is sensed by the contact sense
circuitry
0 = No interrupt
SCIF6 – Low Side Driver Short Circuit Interrupt Flag
This flag indicates a short circuit on PC6 is active and an interrupt
request is pending.
1 = Short circuit at the PC6 pin; PC6 is switched to high impedance
0 = No short circuit at the PC6 pin
