What is non-maskable interrupt example?

Common examples of non-maskable interrupt include types of internal system chipset errors, memory corruption problems, parity errors and high-level errors needing immediate attention. In a sense, a non-maskable interrupt is a way to prioritize certain signals within the operating system.

What is the function of the non-maskable interrupt?

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 meant by marketable interrupt?

an interrupt which can never be turned on or off. Answer:an interrupt that can be turned off by the programmer.

Is reset is maskable interrupt?

Readers will be familiar with the reset button on their computer – it is a high-priority non-maskable interrupt that causes the computer to restart execution from the beginning. The only way to turn it off is to physically disconnect the reset button.

What are the different types of interrupts?

Types of Interrupt

  • Hardware Interrupts. An electronic signal sent from an external device or hardware to communicate with the processor indicating that it requires immediate attention.
  • Software Interrupts.
  • Level-triggered Interrupt.
  • Edge-triggered Interrupt.
  • Shared Interrupt Requests (IRQs)
  • Hybrid.
  • Message–Signalled.
  • Doorbell.

Why are interrupts masked?

If a level-triggered interrupt from a peripheral device is enabled and active, but the kernel trap handler cannot immediately run the device’s interrupt service routine (ISR) to clear the interrupt, the handler masks the interrupt at the GPIO pin to prevent the pin from repeatedly causing more interrupts.

Which interrupt has lowest priority?

Explanation: The interrupt, RI=TI (serial port) is given the lowest priority among all the interrupts.
