u = unchanged, x = unknown, - = unimplemented bit, reads as ‘0’.
Shaded cells are not used by Brown-out Reset.
Other (non Power-up) Resets include MCLR Reset, Brown-out Reset and Watchdog Timer Reset during normal operation.
x = unknown, u = unchanged, - = unimplemented read as ‘0’, q = value depends upon condition.
