Note 1:
Optional multiplexing of CCP2 input/output with RB3 is enabled by selection of configuration bit.
2:
The high order bits of the Direct Address for the RAM are from the BSR register (except for the MOVFF instruction).
3:
Many of the general purpose I/O pins are multiplexed with one or more peripheral module functions. The multiplexing combinations are device dependent. DS39564C-page 8 © 2006 Microchip Technology Inc.
