– = Unimplemented locations read as ‘0’, u = unchanged, x = unknown, q = value depends on condition, shaded = unimplemented
Other (non Power-up) Resets include MCLR Reset and Watchdog Timer Reset during normal operation.
This register is only initialized by a POR or BOR reset and is unchanged by other Resets.
