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 update
If one, the CTRL, HYST and LEVEL values will not be updated again by Flash fuses
Can be cleared to allow subsequent overwriting of the value 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 register.
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
or interrupt.
