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 LEVEL field has been updated by the Flash fuses after power-on reset or Flash fuses update
If one, the LEVEL value will not be updated again by Flash fuses
Can be cleared to allow subsequent overwriting of the value by Flash fuses
0: BOD33 is off
1: BOD33 is enabled and can reset the chip
2: BOD33 is enabled and but cannot reset the chip. Only interrupt will be sent to interrupt controller, if enabled in the IMR
register.
3: BOD33 is off
This field sets the triggering threshold of the BOD33. See Electrical Characteristics for actual voltage levels.
Note that any change to the LEVEL field of the BOD33 register should be done with the BOD33 deactivated to avoid spurious
reset or interrupt.
