= Output
P = Power
I2C = ST with I2C™ or SMB levels
OD = Open-Drain (no P diode to VDD)
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).
6: Default assignment for PMP data and control pins when PMPMX Configuration bit is set.
7: Alternate assignment for PMP data and control pins when PMPMX Configuration bit is cleared (programmed).
