In computer science, a vectored interrupt is a processing technique in which the interrupting device directs the processor to the appropriate interrupt service routine. This is in contrast to a polled interrupt system, in which a single interrupt service routine must determine the source of the interrupt by checking all potential interrupt sources, a slow and relatively laborious process. WebIn general, there are two methods for handling this problem: polled interrupts and vectored interrupts. ... Bits 3 down to 0 will define masks for the three types of interrupts/exceptions.
