摘　　要：本文从TCN标准出发,着重论述多功能车辆总线控制器MVBC内部编程模块的具体功能及主控MVBC在一类设备模式下的初始化配置流程,并在此基础上阐明MVBC一类设备模式下的主/从数据帧的基本组成、帧格式配置、功能码、端口属性定义以及实现数据帧收发的具体方法。通过对MVBC一类模式下的主/从数据帧收发具体流程的详细分析,为进一步开展直接针对MVBC控制器底层硬件的数据通信编程打下基础。This article introduced the MVB bus topology and its type of data transmission. Meanwhile, it was also emphasized the programming structure of MVBC02, the next generation MVB bus communication control chip. On this basis, it was illustrated the basic structure of master/slave frame under class 1 mode and specific implementation method of data transceiver. There was a detailed analysis of classl mode of MVBC of data transmit and receiving process of master/slave frame, in order to lay the foundation of further develop of MVBC hardware data communication.
