I was advised to enable brown-out after encountering EEPROM corruption problems.
I am using atmega328. The brown-out voltages that can be chosen are 4V3, 2V7, 1V8. How do I determine what is the right value to choose to prevent EEPROM corruption? The datasheet says for EEPROM to be written correctly, the supply voltage needs to be of a minimum value but does not say how much this minimum is.
