摘　　要：针对E1单元No.7信令工作方式下的话音呼叫功能的应用需求,利用MPC8280多通道控制器(MCC)的中断处理功能完成了信号单元SU的接收和发送功能。首先介绍了MPC8280处理器的体系架构和MCC的基本工作原理,重点描述了MCC驱动程序的设计方法,解决了MCC的初始化、数据收发处理以及中断处理等关键技术。最后对实现的设备进行了测试,测试结果表明驱动程序性能良好,工作稳定可靠,具有一定的工程实用性。For the application requirement of voice calling function of E1 unit under the mode of No.7 signaling, the receiving and sending functions of signal unit （SU） are achieved by using the interrupt processing function of MPC8280 Multi-Channel Controller （MCC）. Firstly, the architecture of MPC8280 processor and the basic working principle of MCC are introduced, the design method of MCC driver is described, and then some critical technologies such as initialization, data receiving/sending processing and interrupt processing of MCC are achieved. Finally, the test is clone for the implemented device and the test results show that the MCC driver works stably and reliably, has excellent performance, and is practical for engineering.
