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. 2: These registers can be addressed from any bank. 3: Unimplemented, read as ‘1’. |
