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<12:8> whose contents are transferred to the upper byte of the program counter. 2: Other (non Power-up) Resets include external RESET through MCLR and Watchdog Timer Reset. 3: These registers can be addressed from any bank. |
