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 contents 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 28-pin devices, always maintain these bits clear.
These registers can be addressed from any bank.
These registers/bits are not implemented on the 28-pin devices read as '0'.
