NettetAn example of a use for NMI is for a watchdog timer to make sure he system is handling interrupts in a timely manner. The timer sets NMI which sets a flag and a pending interrupt to be taken when there's no interrupts being handled and it is going back to application level.. The pending interrupt then unsets the flag.
