The BOREN0 and BOREN1 bits in the Configuration
Word register select one of three BOR modes.
Selecting BOREN<1:0> = 10, the BOR is automatically
disabled in Sleep to conserve power and enabled on
wake-up. See Register 12-1 for the Configuration Word
definition.
A brown-out occurs when V
greater than parameter T
“Electrical Specifications”). The brown-out condition
will reset the device. This will occur regardless of V
slew rate. A Brown-out Reset may not occur if V
below V
