Legend: x = unknown, u = unchanged, q = value depends on condition, - = unimplemented read as ’0’.
Note 1:
Bank 3
2: Other (non power-up) resets include external reset through MCLR and Watchdog Timer Reset.
3: These registers can be addressed from either bank.
4: The Parallel Slave Port (PORTD and PORTE) is not implemented on the PIC16C745, always maintain these bits clear.

Shaded locations are unimplemented, read as ‘0’.
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.
