Shaded locations are unimplemented, read as ‘0’. Note 1: These registers can be addressed from either bank. 2: 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. 3: Other (non power-up) resets include external reset through MCLR and Watchdog Timer Reset. 4: The IRP and RP1 bits are reserved on the PIC16C715, always maintain these bits clear. |
