12.3.2.1.2 Brownout Detector (BOD) Reset Source

The on-chip Brown-out Detection circuit will monitor the V_DD level during operation by comparing it to a fixed trigger level. The trigger level for the BOD can be selected by fuses. If BOD is unused in application it is forced on to a minimum level in order to guarantee safe operation during internal reset and chip erase.

A BOD Reset will reset all logic.
