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

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 con-

tents are transferred to the upper byte of the program counter.

Other (non power-up) resets include external reset through MCLR and Watchdog Timer Reset.

Bits PSPIE and PSPIF are reserved on the PIC16C76, always maintain these bits clear.

These registers can be addressed from any bank.

PORTD and PORTE are not physically implemented on the PIC16C76, read as ‘0’.
