Zusammenfassung:A data processing system (10) capable of burst transfers having an external bus interface (30) which allows termination of a burst transfer prior to completion of the burst transaction. The present invention offers a method of terminating a burst transaction without the addition of wait states, and further allows termination to effectively interrupt the burst transaction rather than waiting for burst completion. In one embodiment, on the negation of a burst request signal during a burst transfer, external bus interface (30) terminates the burst transfer without waiting for the completion of the burst transaction.
