22.6.5.2 Enabling, Disabling, and Resetting

After power or user reset, the BOD33 and BOD12 register values are loaded from the NVM User Row.

The BODVDD is enabled by writing a '1' to the Enable bit in the BOD control register (BOD33.ENABLE). The BOD is disabled by writing a '0' to the BODVDD.ENABLE.
