Brown-out Reset is enabled by programming the
BOREN<1:0> bits in the Configuration register. The
brown-out trip point is selectable from two trip points
via the BORV bit in the Configuration register.
Between the POR and BOR, complete voltage range
coverage for execution protection can be imple-
mented.
Two bits are used to enable the BOR. When
BOREN = 11, the BOR is always enabled. When
BOREN = 10, the BOR is enabled, but disabled during
