Note 1: Alternate assignment for ECCP2/P2A when CCP2MX Configuration bit is cleared (Extended Microcontroller
mode).
2: Default assignment for ECCP2/P2A for all devices in all operating modes (CCP2MX is set).
3: Default assignments for P1B/P1C/P3B/P3C (ECCPMX Configuration bit is set).
4: Alternate assignment for ECCP2/P2A when CCP2MX is cleared (Microcontroller mode).
5: Alternate assignments for P1B/P1C/P3B/P3C (ECCPMX Configuration bit is cleared).
6: Pin placement when PMPMX = 1.
7: Pin placement when PMPMX = 0.
8: RA7 and RA6 will be disabled if OSC1 and OSC2 are used for the clock function.
