TTL = TTL compatible input; CMOS = CMOS compatible input or output; ST = Schmitt Trigger input with CMOS levels;
I = Input; O = Output; P = Power.
I = Input; O = Output; P = Power.
Note
1:
Default pin assignment for SDO, T3CKI and CCP2 when Configuration bits SDOMX, T3CMX and CCP2MX are set.
2:
Alternate pin assignment for SDO, T3CKI and CCP2 when Configuration bits SDOMX, T3CMX and CCP2MX are clear.
3:
Pin is “No Connect”, except on PIC18(L)F45K50 TQFP devices with ICPRT Configuration bit set.
