— = 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.
GP3 pull-up is enabled when pin is configured as MCLR in the Configuration Word register.
MCLR and WDT Reset do not affect the previous value data latch. The RAIF bit will be cleared upon Reset, but will set
again if the mismatch exists.
