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

Shaded locations are unimplemented, read as ‘0’.

These registers can be addressed from either bank.

The upper byte of the Program Counter (PC) is not directly accessible. PCLATH is a holding register for the PC whose

contents are transferred to the upper byte of the program counter. (PC<12:8>)

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

The BOR bit is reserved on the PIC16C62, always maintain this bit set.

The IRP and RP1 bits are reserved on the PIC16C62/62A/R62, always maintain these bits clear.

PIE1<7:6> and PIR1<7:6> are reserved on the PIC16C62/62A/R62, always maintain these bits clear.
