Interrupt sequence in 8086
WebAn interrupt service routine (ISR) is a software routine that hardware invokes in response to an interrupt. ISR examines an interrupt and determines how to handle it executes the handling, and then returns a logical interrupt value. If no further handling is required the ISR notifies the kernel with a return value. Web4) Sources of Interrupts in 8086. An interrupt in 8086 can come from one of the following three sources. One source is from an external signal applied to NMI or INTRinput pin of …
