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

Shaded locations are unimplemented, read as ‘0’.

Note 1: These registers can be addressed from either 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: Other (non power-up) resets include external reset through MCLR and Watchdog Timer Reset.

4: The IRP and RP1 bits are reserved on the PIC12CE67X, always maintain these bits clear.
