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.
3: Function on PORTD and PORTE for PIC18(L)F4XK22 devices.
