## Bits 2:0 – LVL[2:0]: BOD Level

BOD Level

This bit field controls the BOD threshold level.

The Reset value is loaded from the BOD Level (LVL) bits in the BOD Configuration Fuse (FUSE.BODCFG).

Value Name Typical Values
0x0 BODLEVEL0 1.90V
0x1 BODLEVEL1 2.45V
0x2 BODLEVEL2 2.70V
0x3 BODLEVEL3 2.85V
Other Reserved
Note: BODLEVEL0 will only be enabled during chip erase. During normal operation, writing ‘0x0’ to this bit field will be the same as disabling the BOD.
Note: Values in the Typical Values column are typical values. Refer to the Electrical Characteristics section for further details.
