Alternate assignment for CCP2 when CCP2MX Configuration bit is cleared.
Default assignment for CCP2 when CCP2MX Configuration bit is set.
These pins are No Connect unless the ICPRT Configuration bit is set. For NC/ICPORTS, the pin is No
Connect unless ICPRT is set and the DEBUG Configuration bit is cleared.
