Note 1: Alternate assignment for ECCP2/P2A when Configuration bit, CCP2MX, 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).
