What is an example of non-maskable interrupt?

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.

What is maskable interrupt example?

Maskable Interrupts are those which can be disabled or ignored by the microprocessor. These interrupts are either edge-triggered or level-triggered, so they can be disabled. INTR, RST 7.5, RST 6.5, RST 5.5 are maskable interrupts in 8085 microprocessor.

What is non-maskable interrupt used for?

An NMI is an interrupt which can’t be disabled by clearing the CPU’s interrupt enable flag, unlike most normal interrupts. Non-Maskable interrupts are typically used to signal events that require immediate action, such as a parity error, a hardware failure, or imminent loss of power.

What is the function of trap RST7 5 RST6 5 rst5 5 interrupt?

Interrupts are the signals generated by the external devices to request the microprocessor to perform a task. There are 5 interrupt signals, i.e. TRAP, RST 7.5, RST 6.5, RST 5.5, and INTR. Vector interrupt − In this type of interrupt, the interrupt address is known to the processor. For example: RST7.

Which of the following interrupts are non-maskable interrupts Mcq?

Which interrupt is unmaskable? Explanation: The trap is a non-maskable interrupt as it deals with the ongoing process in the processor. The trap is initiated by the process being executed due to lack of data required for its completion. Hence trap is unmaskable.

Which of the following interrupt is an non-maskable interrupt?

A non-maskable is an interrupt which can not be disabled. RST 7.5, RST 5.5 are maskable interrupts but TRAP is a non-maskable interrupt.

What is the difference between traps and interrupts?

There are two kinds of events: traps and interrupts. The difference between a trap and an interrupt is that a trap is triggered by a user program to invoke OS functionality. Still, an interrupt is triggered by a hardware device to allow the processor to execute the corresponding interrupt handler routine.

What is a non-maskable interrupt?

On most architectures, non maskable interrupts are related to unrecoverable hardware errors like memory corruption. Some events like triggering of watchdog timers etc are also in to interfaced to NMI pin of the microprocessor. Most I/O devices like storage, networking and peripherals are interfaced via maskable interrtupts mechanism.

What are the different types of interrupt?

1. Maskable Interrupt : An Interrupt that can be disabled or ignored by the instructions of CPU are called as Maskable Interrupt.The interrupts are either edge-triggered or level-triggered or level-triggered. 2. Non-Maskable Interrupt :

Which of the following is a non-maskable interrupt in 8085 microprocessor?

INTR, RST 7.5, RST 6.5, RST 5.5 are maskable interrupts in 8085 microprocessor. Non-Maskable Interrupts are those which cannot be disabled or ignored by microprocessor. TRAP is a non-maskable interrupt. It consists of both level as well as edge triggering and is used in critical power failure conditions.

Why trap is not an interrupt?

TRAP is usually not an interrupt but an exception that is synchronous in nature. They happen when events like divide by zero and invalid memory access happen. These can not be masked as they are generated due to internal state of processor execution and not by an external device. What are “interrupts”?
