Shaded locations are unimplemented, read as ‘0’.
Note
1:
The upper byte of the program counter is not directly accessible. PCLATH is a holding register for the PC<12:8> whose contents are
transferred to the upper byte of the program counter.
2:
These registers can be addressed from any bank.
3:
These bits are reserved; always maintain these bits clear.
