Legend: x = unknown, u = unchanged, q = value depends on condition, - = unimplemented read as '0'.
Shaded locations are 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> whose con-
tents 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:
Bits PSPIE and PSPIF are reserved on the PIC16C73/73A, always maintain these bits clear.
4:
These registers can be addressed from either bank.
5:
PORTD and PORTE are not physically implemented on the PIC16C73/73A, read as ‘0’.
6:
Brown-out Reset is not implemented on the PIC16C73 or the PIC16C74, read as '0'.
7:
The IRP and RP1 bits are reserved on the PIC16C73/73A/74/74A, always maintain these bits clear.
