An input change on any port pins that support IOC sets Flag bit,
IOCIF. The
interrupt can be enabled/disabled by setting/clearing the enable bit, IOCIE. Pins must
also be individually enabled in the IOCxP and IOCxN register. IOCIF is a
read-only bit and the flag can be cleared by clearing the corresponding IOCxF registers.
