Alternate assignment for CCP2 in all operating modes except Microcontroller – applies to PIC18F8X8X only.
Default assignment when CCP2MX is set.
External memory interface functions are only available on PIC18F8X8X 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 PIC18F8X8X (80-pin) devices.
PSP is available in Microcontroller mode only.
On PIC18F8X8X devices, these pins can be multiplexed with RH7/RH6 by changing the ECCPMX
configuration bit.
