    • 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.
    • 用于在电子系统中实现柔性中断机制的系统和方法包括可以最初执行用于执行中断配置过程的初始化例程(220)的处理器(114)。 当处理器(114)使用可用于灵活地配置电子系统中的中断模块(210)的某些可选择的中断参数来编程配置寄存器(510)时,可以优选地启动前述中断配置过程。 内部和外部中断源(134)随后可以随后向所配置的中断模块(210)提供各种中断,其可以基于在前述中断配置过程期间提供的中断信息来响应地检测和路由中断到处理器(114)。 然后,处理器(114)可以通过利用相应的中断处理程序在适当的中断服务过程中有效地服务中断。
