ＰＳ／２通讯协议是一种双向同步串行通讯协议。通讯的两端通过Ｃｌｏｃｋ（时钟脚）同步，并通过Ｄａｔａ（数据脚）交换数据。任何一方如果想抑制另外一方通讯时，只需要把Ｃｌｏｃｋ（时钟脚）拉到低电平。一般两设备间传输数据的最大时钟频率是３３ｋＨｚ，大多数ＰＳ／２设备工作在１０～２０ｋＨｚ。推荐值在１５ｋＨｚ左右，也就是说，Ｃｌｏｃｋ（时钟脚）高、低电平的持续时间都为４０μｓ。每一数据帧包含１１～１２个位。
-PS/2 communication protocol is a bi-directional synchronous serial communication protocol. Communication at both ends through the Clock (the clock pin) synchronization, and Data (data pin) to exchange data. If you want to inhibit any of the parties the other party of communication, just to Clock (Clock feet) down low. The general transmission of data between two devices of the maximum clock frequency is 33kHz, the majority of PS/2 devices work in the 10 ~ 20kHz. Recommended value of around 15kHz, which means, Clock (Clock feet) high, low for the duration of 40μs. Each data fr a me contains 11 ~ 12-bit.
