It is a maskable interrupt, having the lowest priority among all interrupts.

It can be disabled by resetting the microprocessor.

The microprocessor checks the status of INTR signal during the execution of each instruction..

Which interrupt is Unmaskable?

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.

Whenever an interrupt occurs, the controller completes the execution of the current instruction and starts the execution of an Interrupt Service Routine (ISR) or Interrupt Handler.

What are interrupts and its types?

TYPES OF INTERRUPTS Maskable Interrupt: The hardware interrupts which can be delayed when a much highest priority interrupt has occurred to the processor. Non Maskable Interrupt: The hardware which cannot be delayed and should process by the processor immediately.

Why do interrupts have priorities?

A priority interrupt is a system which decides the priority at which various devices, which generates the interrupt signal at the same time, will be serviced by the CPU. The system has authority to decide which conditions are allowed to interrupt the CPU, while some other interrupt is being serviced.
