Which is non-maskable interrupt?

Which is non-maskable interrupt?

In computing, a non-maskable interrupt (NMI) is a hardware interrupt that standard interrupt-masking techniques in the system cannot ignore. Such uses include reporting non-recoverable hardware errors, system debugging and profiling, and handling of special cases like system resets.

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.

Which of the following is non-maskable interrupt in 8086?

TRAP of 8086 is an example of Non Maskable interrupt.

What is maskable and non-maskable interrupts?

1. Maskable interrupt is a hardware Interrupt that can be disabled or ignored by the instructions of CPU. A non-maskable interrupt is a hardware interrupt that cannot be disabled or ignored by the instructions of CPU.

What are maskable and non-maskable interrupts give examples how will you mask an interrupt in 8086?

The 8086 has two hardware interrupt pins, i.e. NMI and INTR. NMI is a non-maskable interrupt and INTR is a maskable interrupt having lower priority. One more interrupt pin associated is INTA called interrupt acknowledge.

What is meant by maskable interrupts Mcq?

Answer:an interrupt that can be turned off by the programmer.

What do you mean by maskable and non maskable interrupts explain them with example differentiate between RIM and SIM?

In brief, maskable and non-maskable interrupts are two types of interrupts. The main difference between maskable and non maskable interrupt is that maskable interrupt can be disabled or ignored by the CPU while non-maskable interrupt cannot be disabled or ignored by the CPU.

What are maskable and non maskable interrupts give examples how will you mask an interrupt in 8086?

Which is the non maskable interrupt Mcq?

Types of Interrupts MCQ Question 4 Detailed Solution

MASKABLE INTERRUPT	NON MASKABLE INTERRUPT
Lower priority than non-maskable interrupt	Higher priority than maskable interrupt
May be vectored and non-vectored	All are vectored
Used to interface with peripheral device	Used for emergency purpose

What is meant by a maskable interrupt?

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.

What are maskable and non-maskable interrupts in 8085 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. Non-Maskable Interrupts are those which cannot be disabled or ignored by microprocessor. TRAP is a non-maskable interrupt.

What is the difference between maskable and non-maskable interrupts?

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. Non-Maskable Interrupts are those which cannot be disabled or ignored by microprocessor.

Which of the following is only non-vectored interrupt in 8085 microprocessor?

INTR is the only non-vectored interrupt in 8085 microprocessor. 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 are interrupts in microprocessor?

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. Interrupt are classified into following groups based on their parameter −
