Interruption processing circuit for receiving and storing data associated with an event

摘要

An object of the present invention is to provide an interruption processing circuit which can send out an interruption information correctly to a data processor even when timing of occurrence of an interruption event is overlapped with that of its reading. An event signal indicating the occurrence of an interruption event is read and held in accordance with timing of the occurrence of an event or starting timing of data processing in a data processor and furthermore the signal held here is read and held in accordance with the subsequent processing start timing and sent out to a data processor in response to a readout signal fed by a data processor.
