x = unknown, u = unchanged, q = value depends on condition, - = unimplemented, read as '0', r = reserved.
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.
PORTD, PORTE, TRISD and TRISE are not physically implemented on the 28-pin devices, read as ‘0’.
