Brown-out Reset is enabled by programming the
BOREN<1:0> bits in the Configuration register.
Between the POR and BOR, complete voltage range

implemented.
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
Sleep. When BOREN = 0X, the BOR is disabled.
