WebThe software assigns each interrupt to a handler in the interrupt table. An interrupt handler is just a routine containing a sequence of operations. Each of these may request input and output while running. The routine for handling a specific interrupt is known as the interrupt service routine for the specific interrupt. WebISR is also called Interrupt Handler. Interrupts are recognized and serviced by CPU at the end of the current instruction execution. Context switching of the Processor happens … Web9.6 Interrupt Tasks and Interrupt Procedures Just as a CALL instruction can call either a procedure or a task, so an interrupt or exception can "call" an interrupt handler that is either a procedure or a task. When responding to an interrupt or exception, the processor uses the interrupt or exception identifier to index a descriptor in the IDT. round 302.940 to the nearest hundredth
