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.
Bits PSPIE and PSPIF are reserved on PIC16F873A/876A devices; always maintain these bits clear.
These registers can be addressed from any bank.
PORTD, PORTE, TRISD and TRISE are not implemented on PIC16F873A/876A devices, read as ‘0’.
Bit 4 of EEADRH implemented only on the PIC16F876A/877A devices.
