PURPOSE: A device for processing a vectored-interrupt of an auto vector method microprocessor is provided to make an interrupt be processed normally between a microprocessor which does not supply an interrupt process of a vectored-interrupt method and a peripheral element being operated as a vectored-interrupt method. CONSTITUTION: While an interrupt cycle is progressed automatically in a microprocessor(10), an interrupt control unit(22) transmits an interrupt confirmation signal necessary for terminating the interrupt cycle with respect to an interrupt requesting signal of the peripheral element to a peripheral element(30). When an interrupt is recognized, an interrupt service is started as an auto vector, and an access of the peripheral element(30) is necessary, a chip selection unit(21) monitors whether a normal access is possible or not by terminating the interrupt cycle of the peripheral element(30). A microprocessor mal-function preventing unit prevents data(interrupt vector) unnecessary for a microprocessor operation and a data confirmation signal from being transmitted.
