The datasheet for each microcontroller the settings.

To summarize, BODEN is an abbreviation for Brown Out Detector ENable.  
If brown-out detection is enabled, the other setting (BODLEVEL)
determines the actual voltage level below which the brown-out detector 
will be triggered, i.e. 2.7 volts or 4.0 volts.  Which of these levels 
you choose depends on your particular application.
