Explanation: 

Detailed explanation-1: -When an interrupt occurs, it causes the CPU to stop executing the current program. The control then passes to a special piece of code called an Interrupt Handler or Interrupt Service Routine. The interrupt handler will process the interrupt and resume the interrupted program.

Detailed explanation-2: -A device invokes a level-triggered interrupt by driving the signal to and holding it at the active level. It negates the signal when the processor commands it to do so, typically after the device has been serviced. The processor samples the interrupt input signal during each instruction cycle.

Detailed explanation-3: -Suspension. Execution of the current program is suspended. Obtaining ISR Address. Jump to ISR. Suspension Execute ISR. Resumption. 01-Aug-2021
