7.2.3 BOR CONTROLLED BY SOFTWARE
When the BOREN bits of Configuration Word 1 are set
to ‘01’, the BOR is controlled by the SBOREN bit of the
BORCON register. The device start-up is not delayed
by the BOR ready condition or the V
DD level.
BOR protection begins as soon as the BOR circuit is
ready. The status of the BOR circuit is reflected in the
BORRDY bit of the BORCON register.
BOR protection is unchanged by Sleep.
