The upper byte of the program counter is not directly accessible. PCLATH is a holding register for the PC<14:8>, 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 PIC16F1933/1936/1938/PIC16LF1933/1936/1938 devices, read as ‘0’.
Name
x = unknown, u = unchanged, q = value depends on condition, - = unimplemented, read as ‘0’, r = reserved.
Shaded locations are unimplemented, read as ‘0’.
