摘要：
A communications system (100) includes a communications channel (101), a first processing unit (115), an interface unit (120), and an interrupt controller (210). The first processing unit (115) is adapted to monitor the communications channel (101) and provide a plurality of status bits. The interface unit (120) includes an interrupt register (215). The interrupt controller (210) is adapted to identify a plurality of interrupts in response to changes in the status bits. Each interrupt has a priority, and the interrupt controller (210) is adapted to store selected interrupts in the interrupt register (215) in an order determined by the priority of the interrupts. A method includes monitoring a communications channel (101). A plurality of status bits associated with the monitoring are provided. A plurality of interrupts are identified based on changes in the status bits, each interrupt having a priority. Selected interrupts are stored in an interrupt queue (22, 225, 230) in an order determined by the priority of the interrupts.
摘要（中）：
通信系统（100）包括通信信道（101），第一处理单元（115），接口单元（120）和中断控制器（210）。 第一处理单元（115）适于监视通信信道（101）并提供多个状态位。 接口单元（120）包括中断寄存器（215）。 中断控制器（210）适于响应于状态位的改变来识别多个中断。 每个中断具有优先权，并且中断控制器（210）适于以中断的优先级确定的顺序将选择的中断存储在中断寄存器（215）中。 一种方法包括监视通信信道（101）。 提供与监视相关联的多个状态位。 基于状态位的变化来识别多个中断，每个中断具有优先权。 所选择的中断按照中断优先级确定的顺序存储在中断队列（22,225,230）中。
