x= unknown, u= unchanged, q= value depends on condition, - = unimplemented, read as ‘0’, r= reserved.
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<14:8>, whose contents are transferred
to the upper byte of the program counter.
2: These registers can be addressed from any bank.
