    Non-maskable interrupt From Wikipedia, the free encyclopedia In computing, a non-maskable interrupt (NMI) is a hardware interrupt that standard interrupt-masking techniques in the system cannot ignore. It typically occurs to signal attention for non-recoverable hardware errors.

    What is a non maskable interrupt?
    Non Maskable Interrupt. The NMI ("Non Maskable Interrupt") is a hardware-driven interrupt much like the PIC interrupts, but the NMI goes either directly to the CPU, or via another controller (e.g., the ISP)---in which case you can mask them. NMI occur for RAM errors and unrecoverable hardware problems.

    What is an interrupt-driven system?
    Systems that use interrupts in these ways are said to be interrupt-driven. Interrupt signals may be issued in response to hardware or software events. These are classified as hardware interrupts or software interrupts, respectively. For any particular processor, the number of interrupt types is limited by the architecture.

    How do interrupts work in an internal interrupt mask register?
    Processors typically have an internal interrupt mask register, which allows selective enabling (and disabling) of hardware interrupts. Each interrupt signal is associated with a bit in the mask register.

    What is the difference between masking and unmasking?
    To mask an interrupt is to disable it, while to unmask an interrupt is to enable it. Processors typically have an internal interrupt mask register, which allows selective enabling (and disabling) of hardware interrupts. Each interrupt signal is associated with a bit in the mask register.

    https://it.wikipedia.org/wiki/Non-maskable_interrupt

    Nell'architettura dei calcolatori, un non-maskable interrupt ("interruzione non mascherabile", abbreviato in NMI) è un particolare tipo di segnale di interrupt che non può essere ignorato ("mascherato") dalla CPU.
    Un interrupt di questo tipo può essere usato per segnalare malfunzionamenti irrecuperabili delle componenti hardware del computer. È un segnale asincrono, poiché potrebbe avvenire in qualsias…

    https://en.wikipedia.org/wiki/Interrupt
    • In digital computers, an interrupt is a request for the processor to interrupt currently executing code, so that the event can be processed in a timely manner. If the request is accepted, the processor will suspend its current activities, save its state, and execute a function called an interrupt handler to deal with the event. This interruption is often temporary, allowing the softwa…

    • The 64 with its 6510 CPU supports two different types of interrupt; Interrupt ReQuest (IRQ) and Non-Maskable Interrupt(NMI). Each type has a host of hardware devices in the C64 that may supply the prompting signal to the CPU. The "official" difference is that the CPU has the option of ignoring the IRQ type, whereas it is forced to respond to an NMI. Unofficially, there are ways to di…

      Löst ein Gerät einen nichtmaskierbaren Interrupt aus (engl. „non-maskable interrupt“, kurz NMI), so wird dem NMI-Anschluss des Prozessors ein aktives Signal zugeführt. Der Prozessor arbeitet den gerade ausgeübten Befehl ab und führt unmittelbar danach einen Interrupt durch.
