Note 1:
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.
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.
