Legend:

Note 1:

2:

– = 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.

MCLR and WDT Reset does not affect the previous value data latch. The RAIF bit will be cleared upon Reset but will set again if the

mismatched exists.
