Legend: x = unknown, u = unchanged, q = value depends on condition, - = unimplemented, read as '0'.

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 trans-

ferred to the upper byte of the program counter. See Section 2.9 for more detail.

2: These registers can be addressed from any bank.
