AD转换器的模拟信号仿真，写控制字, 再通过通信寄存器对设置寄存器、时钟寄存器进行访问。分别写控制字05H和40H、FFH,表示AD晶振2. 4576MHz, 更新频率60次/ s, 自校准模式, 差分输入。-AD converter analog simulation　Write control word, again through the communication registers on Settings registers, clock registers visit. Write control words respectively in H and 40 H, FFH, said AD crystals 2. 4576 MHz, the frequency of updates 60 times/s, the calibration model, differential input.
