Legend:

Note 1:

2:

3:

4:

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<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 PIC16(L)F1936 devices, read as ‘0’.

Unimplemented, read as ‘1’.
