NMI

NMI stands for Non-Maskable Interrupt, which is a type of interrupt that cannot be ignored or masked by the processor. It is a high-priority interrupt that typically occurs when a critical error or hardware failure is detected. NMI interrupts are used to handle important system events that require immediate attention, such as memory errors, power failures, or system crashes. The NMI signal ensures that these events are promptly addressed, allowing for system stability and reliability.
