12.6
The BODEN0 and BODEN1 bits in the Configuration
Word register select one of four BOD modes. Two
modes have been added to allow software or hardware
control of the BOD enable. When BODEN<1:0> = 01,
the SBODEN bit (PCON<4>) enables/disables the BOD
allowing it to be controlled in software. By selecting
BODEN<1:0>, the BOD is automatically disabled in
Sleep to conserve power and enabled on wake-up. In
this mode, the SBODEN bit is disabled. See
Register 12-1 for the Configuration Word definition.

On any Reset (Power-on, Brown-out Detect, Watchdog
