摘要：
In a data processing system, interrupt service is provided for any one of a plurality of interrupt sources which presents an interrupt signal which has a higher interrupt level than that of the currently active source. Interrupt flags are provided for each potential interrupt source, which flags are activated in response to the receipt of an interrupt signal from the interrupt source associated therewith. A scan for the highest interrupt level is made and interrupt service is provided for the interrupt source associated therewith.
