[assembly language] time

Description: 可编程间隔定时器（Programmable Interval Timer，PIT， 8253或8254模型），也叫做系统时钟，是一个非常有用的芯片，可以在一定时间间隔精确地产生中断。芯片本身有3个通道：通道0绑定到IRQ0，在可预知和规则的时间中断CPU；通道1特定于系统；通道2则连接到系统扬声器。就像你看到的一样，单个的芯片为系统提供了几个非常重要的服务。

[Windows Develop] 8254

Description: This is a photo of a general purpose timer/counter card you can wirewrap in a weekend. It plugs into your PC s ISA bus just like a sound or modem card. It gives high-resolution timing (microseconds). Because of its programmablity, it is very powerful and flexible. You can even control DC or servo motors using pulse-width modulated (PWM), or stepper motors using its square wave capabilities. The figure below is the actual output (square wave) from the 8254 card captured by an oscilloscope:
