Application Use Case for BOD - Application

The preferred method of setting BOD33 levels and settings is through the fuses. When it is desirable to set it in software, see the below use case.

In this use case, a new BOD33 level might be set in SW if the clock settings are adjusted up after a battery has charged to a higher level. When the battery discharges, the chip will reset when the battery level is below SW BOD33 level. Now the chip will run at a lower clock rate and the BOD33 level from fuse. The chip should always measure the voltage before adjusting the frequency up.
