代码说明：

  TLC2543C和TLC2543I是12位、开关电容器、逐次逼近、模拟数字转换器。每个设备有三个控制 输入[芯片选择（CS），输入输出时钟（I/O 时钟）和地址输入（数据输入）] 设计用于与串行通信 主机处理器或外设通过 串行3态输出。该设备允许高速 从主机传输数据。 报错(The TLC2543C and TLC2543I are 12-bit, switchedcapacitor, successive-approximation, analog-todigital converters. Each device has three control inputs [chip select (CS), the input-output clock (I/O CLOCK), and the address input (DATA INPUT)] and is designed for communication with the serial port of a host processor or peripheral through a serial 3-state output. The device allows high-speed data transfers from the host.)
