Legend: x = unknown, u = unchanged, q = value depends on condition, - = 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>.

2: The IRP and RP1 bits are reserved; always maintain these bits clear.
3: Other (non power-up) RESETS include external RESET through MCLR and Watchdog Timer Reset.
4: These registers can be addressed from either bank.
5: PORTD, PORTE and the parallel slave port are not implemented on the PIC16C63A/73B; always maintain these bits and
6: The A/D is not implemented on the PIC16C63A/65B; always maintain these bits and registers clear.
