• This field must be written twice, first with key value 0x55, then 0xAA, for a write operation to have an effect.
• Set to 1 when CTRL, HYST and LEVEL fields has been updated by the Flash fuses after power-on reset or Flash fuses
• 0: Allow subsequent overwriting of the value by Flash fuses.
• 1: The CTRL, HYST and LEVEL values will not be updated again by Flash fuses.
• 0: BOD is off.
• 1: BOD is enabled and can reset the chip.
• 2: BOD is enabled and but cannot reset the chip. Only interrupt will be sent to interrupt controller, if enabled in the IMR
• 3: BOD is off.
• 0: No hysteresis
• 1: Hysteresis On
• This field sets the triggering threshold of the BOD. See Electrical Characteristics for actual voltage levels.
• Note that any change to the LEVEL field of the BOD register should be done with the BOD deactivated to avoid spurious reset
