2: The upper byte of the program counter is not directly accessible. PCLATH is a holding register for the PC<12:8> whose
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.
