VSS

P

— Ground reference for logic and I/O pins.

Legend: TTL = TTL compatible input CMOS = CMOS compatible input or output; ST = Schmitt Trigger input with CMOS levels;

I = Input; O = Output; P = Power.

Note 1: Default pin assignment for P2B, T3CKI, CCP3 and CCP2 when Configuration bits PB2MX, T3CMX, CCP3MX and

CCP2MX are set.

2: Alternate pin assignment for P2B, T3CKI, CCP3 and CCP2 when Configuration bits PB2MX, T3CMX, CCP3MX and

CCP2MX are clear.
