Explanation:
Detailed explanation-1: -The non-maskable interrupt (NMI) is a special hardware interrupt that is connected to the NMI pin of the CPU. The NMI is assigned an interrupt number of 2, although, since it cannot be masked by other interrupts, it effectively has the highest priority and is designed to be recognised in the shortest possible time.
Detailed explanation-2: -The most common use of NMI is to signal a parity error from the memory subsystem. This error must be dealt with immediately to prevent possible data corruption. How to use it is up to the user. You’ll need to write some special code or program to send an NMI signal.
