Alternate assignment for CCP2 when CCP2MX is not selected (all operating modes except
Microcontroller).
Default assignment when CCP2MX is set.
External memory interface functions are only available on PIC18F8X20 devices.
CCP2 is multiplexed with this pin by default when configured in Microcontroller mode. Otherwise, it is
multiplexed with either RB3 or RC1.
PORTH and PORTJ are only available on PIC18F8X20 (80-pin) devices.
AV
