Note 1:

2:

x = unknown, u = unchanged, – = unimplemented locations read as ‘0’. Shaded cells are not used by

oscillators.

Other (non Power-up) Resets include MCLR Reset and Watchdog Timer Reset during normal operation.

See Configuration Word Register 1 (Register 10-1) for operation of all register bits.
