ABSTRACT:
In a processor-based system, priorities are established among a plurality of interrupt sources by grouping the interrupt sources in accordance with an operating condition of the system. The assignment of the interrupt sources into groups is accomplished through programmable registers which associate flag locations in an interrupt status register with flag locations in a group status register. The operating condition upon which the grouping of interrupt sources is based may be the handling of a particular interrupt, based upon which a next expected interrupt source is assigned to a high priority group.
