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.
These registers can be addressed from any bank.
These registers/bits are not implemented on PIC16F722/723/726/PIC16LF722/723/726 devices, read as ‘0’.
Accessible only when SSPM<3:0> = 1001.
Accessible only when SSPM<3:0> ≠ 1001.
This bit is always ‘1’ as RE3 is input only.
