When a POR reset occurs, the PWRT delay starts (if
enabled). When PWRT ends, the OST counts 1024
oscillator cycles (LP, XT, HS modes only). When OST
completes, the device comes out of reset. The total
time-out will vary based on oscillator configuration and
the status of the PWRT. For example, in RC mode with
the PWRT disabled, there will be no time-out at all.
If MCLR is kept low long enough, the time-outs will
expire. Bringing MCLR high will begin execution imme-
diately. This is useful for testing purposes or to synchro-
nize more than one PIC16CXXX device operating in
parallel.

The BOR bit is unknown on Power-on Reset. If the
Brown-out Reset circuit is used, the BOR bit must be
set by the user and checked on subsequent resets to
see if it was cleared, indicating a Brown-out has
occurred.
POR (Power-on Reset Status bit) is cleared on a
Power-on Reset and unaffected otherwise. The user
