Shaded locations are unimplemented, read as ‘0’.
Note
1:
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.
to the upper byte of the program counter.
2:
These registers can be addressed from any bank.
3:
These registers/bits are not implemented on PIC16(L)F1936 devices, read as ‘0’.
4:
Unimplemented, read as ‘1’.
