这是一个单片机应用中编写键盘代码时可以对比参考的，PS2接口的键盘对应的按键码，很实用的，有用到得朋友可以看看。-This is a microcontroller application can write code in contrast to the keyboard reference, PS2 keyboard interface, the corresponding key code, very practical and useful to have a friend take a look at.

There are many different (and often confusing) terms associated with clock-based devices. This application note attempts to clarify these terms, and hence serves as a comprehensive reference on clock terminology. This application note can be divided into two sections. The first section describes and distinguishes between various clock sources available today. The second section defines and distinguishes between various parameters used to describe clocks. This section also provides methods of measuring some of these parameters.
