//工作时序
//当cs由高变低时，选中ADC0832。在时钟的上升沿，DI端的数据移入ADC0832内部的多路地址移位寄存器。
//在第一个时钟期间，Dl为高，表示启动位，紧接着输入两位配置位。当输入启动位和配置位后，选通输入模拟通道，转换开始。
//转换开始后，经过一个时钟周期延迟，以使选定的通道稳定。ADC0832接着在第4个时钟下降沿输出转换数据。
//数据输出时先输出最高位(D7~DO)；输出完转换结果后，又以最低位开始重新输出一遍数据(D7～DO)，两次发送的最低位共用。当片选cS
//为高时，内部所有寄存器清0，输出变为高阻态。如果要再进行一次模傲转换，片选cs必须再次从高向低跳变，后面再输入启动位和配置位
