13.0 BROWN-OUT DETECTOR
V
The on-chip brown-out detection circuitry resets the
dd
device when V
dips below the specified brown-out volt-
dd
age. The device is held in reset as long as V
stays
dd
D
below the brown-out voltage. The device will come out of
R
R1
reset when V
rises above the brown-out voltage. The
dd
MCLR
brown-out level is preset to approximately 4.2V at the
C
factory. The brown-out circuit can be disabled through
BOR0 and BOR1 bits contained in the FUSEX Word reg-
ister.
