摘　　要：针对I^2C模块作为芯片中必要的基础模块,在芯片的启动、调试及监测中起重要作用,I^2C模块的应用也极为重要。在芯片上电启动/复位时进入Boot模式,I^2C模块从EEPROM中读取初始化配置信息并完成寄存器配置,完成芯片的初始化设置。在调试过程中作为从模式时,外部主机设备可通过I^2C模块访问芯片内部寄存器,完成对芯片的监测、配置和调试。为了提高芯片操控的效率,提出通过I^2C接口配置芯片内部寄存器进入主模式,可读写I^2C总线上从设备的数据。I^2C module,as a necessary basic module in the chip,plays an important role in the start-up,debugging and monitoring of the chip,and the application of I^2C module is also very important.When the chip is powered on and started/reset,the I^2C module reads the initialization configuration information from EEPROM and completes the register configuration to complete the initialization setting of the chip.In the debugging process,as a slave mode,the external host device can access the internal registers of the chip through I^2C module to complete the monitoring,configuration and debugging of the chip.In order to improve the efficiency of chip control,this paper proposes to configure the internal registers of the chip to enter the main mode through I^2C interface,so as to read and write the data of slave devices on I^2C bus.
