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/P3A and CCP2/P2A when Configuration bits PB2MX, T3CMX, CCP3MX

and CCP2MX are set.

2: Alternate pin assignment for P2B, T3CKI, CCP3/P3A and CCP2/P2A when Configuration bits PB2MX, T3CMX,

CCP3MX and CCP2MX are clear.
