Note 1: Alternate assignment for CCP2 in all operating modes except Microcontroller – applies to PIC18F8X8X only.
2: Default assignment when CCP2MX is set.
3: External memory interface functions are only available on PIC18F8X8X devices.
4: CCP2 is multiplexed with this pin by default when configured in Microcontroller mode; otherwise, it is
multiplexed with either RB3 or RC1.
5: PORTH and PORTJ are only available on PIC18F8X8X (80-pin) devices.
6: PSP is available in Microcontroller mode only.
7: On PIC18F8X8X devices, these pins can be multiplexed with RH7/RH6 by changing the ECCPMX
configuration bit.
