The BOREN0 and BOREN1 bits in the Configuration
Word Register 1 select one of four BOR modes. Two
modes have been added to allow software or hardware
control of the BOR enable. When BOREN<1:0> = 01,
the SBOREN bit (PCON<4>) enables/disables the
BOR allowing it to be controlled in software. By
selecting BOREN<1:0>, the BOR is automatically
disabled in Sleep to conserve power and enabled on
wake-up. In this mode, the SBOREN bit is disabled.

The BOR4V bit in the Configuration Word Register 2
selects one of two Brown-out Reset voltages. When
BOR4B = 1, V
