Firing and Handling BOD Interrupt on STM32F746-Discovery
Does anybody know how to fire and or handle a brownout detection interrupt?
I am powering my STM32F746-Discovery with an external power source. When the voltage of the power source drops below a certain point the screen starts to flicker and the processors internal flash memory is erased and or corrupted. Therefore, I am looking for a solution that will only allow the processor to continue to boot after it has reached a certain voltage.
Using the STM-Link utility I noticed that the BOD option byte for my processor was set to level 3.
But what should I do next? I have no idea what the ISR function prototype is like nor do I have an idea if an interrupt is fired at all.
