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.
Accessible only when SSPM<3:0> = 1001.
This bit is unimplemented and reads as ‘1’.
See Register 6-2.
