Legend: x = unknown, u = unchanged, q = value depends on condition, - = unimplemented, read as â0â, r = reserved.

Shaded locations are unimplemented, read as â0â.

Note 1: These registers can be addressed from any bank.

2: 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.

3: This bit always reads as a â1â.
