SYSTEM AND METHOD FOR IMPLEMENTING A FLEXIBLE INTERRUPT MECHANISM

摘要

A system and method for omplementing a flexible interrupt mechanism in an electronic system includes a processor (114) that may initially execute an initialization routine (220) for performing an interrupt configuration procedure. The foregoing interrupt configuration procedure may preferably be initiated when the processor (114) programs a configuration register (510) with certain selectable interrupt parameters that may be utilized to flexibly configure an interrupt module (210) in the electronic system. Internal and external interrupt sources (134) may then subsequently provide various interrupts to the configured interrupt module (210) which may responsively detect and route the interrupts to the processor (114) based upon interrupt information provided during the foregoing interrupt configuration procedure. The processor (114) may then effectively service the interrupts during appropriate interrupt servicing procedures by utilizing corresponding interrupt handler routines.
