BOD

Brown-out detector (BOD) is a voltage monitoring circuit whose functions include BOD Reset and BOD Interrupt. BOD Reset circuit puts the system into reset state when the supply falls below the Brown-Out Reset threshold. BOD Interrupt circuit is used to indicate the application when the supply voltage drops below the configured interrupt threshold. BOD Interrupt circuit will be prompted in two stages. When the supply voltage drops below the configured interrupt threshold, BOD_ASSERT_IRQn is triggered. When the voltage rises above the sum of the hysteresis voltage and the configured interrupt threshold, BOD_DEASSERT_IRQn is triggered.
