  2. Interrupt - Wikipedia

    en.wikipedia.org/wiki/Interrupt

    To mask an interrupt is to disable it, so it is deferred [b] or ignored [c] by the processor, while to unmask an interrupt is to enable it. [9] Processors typically have an internal interrupt mask register, [d] which allows selective enabling [2] (and disabling) of hardware interrupts. Each interrupt signal is associated with a bit in the mask ...

  3. Interrupt flag - Wikipedia

    en.wikipedia.org/wiki/Interrupt_flag

    The Interrupt flag (IF) is a flag bit in the CPU's FLAGS register, which determines whether or not the (CPU) will respond immediately to maskable hardware interrupts. [1] If the flag is set to 1 maskable interrupts are enabled. If reset (set to 0) such interrupts will be disabled until

  4. Non-maskable interrupt - Wikipedia

    en.wikipedia.org/wiki/Non-maskable_interrupt

    With regard to SPARC, the non-maskable interrupt (NMI), despite having the highest priority among interrupts, can be prevented from occurring through the use of an interrupt mask. [1] An NMI is often used when response time is critical or when an interrupt should never be disabled during normal system operation.

  5. Interrupts in 65xx processors - Wikipedia

    en.wikipedia.org/wiki/Interrupts_in_65xx_processors

    A well-designed and succinct interrupt handler or interrupt service routine (ISR) will not only expeditiously service any event that causes an interrupt, it will do so without interfering in any way with the interrupted foreground task—the ISR must be "transparent" to the interrupted task (although exceptions may apply in specialized cases ...

  6. Control register - Wikipedia

    en.wikipedia.org/wiki/Control_register

    If set, enables support for the virtual interrupt flag (VIF) in virtual-8086 mode. 1: PVI: Protected-mode Virtual Interrupts: If set, enables support for the virtual interrupt flag (VIF) in protected mode. 2: TSD: Time Stamp Disable: If set, RDTSC instruction can only be executed when in ring 0, otherwise RDTSC can be used at any privilege ...

  7. Programmable interrupt controller - Wikipedia

    en.wikipedia.org/wiki/Programmable_interrupt...

    PICs typically have a common set of registers: interrupt request register (IRR), in-service register (ISR), and interrupt mask register (IMR). The IRR specifies which interrupts are pending acknowledgement, and is typically a symbolic register which can not be directly accessed.

  9. FLAGS register - Wikipedia

    en.wikipedia.org/wiki/FLAGS_register

    The FLAGS register is the status register that contains the current state of an x86 CPU.The size and meanings of the flag bits are architecture dependent. It usually reflects the result of arithmetic operations as well as information about restrictions placed on the CPU operation at the current time.
