说明：  本文从介绍DVCC8086十六位微型机的硬件组成开始，讨论了十六位微机实验系统的输入输出的相关内容。描述DVCC8086十六位微型机本身的所有资源，同时也对本设计中使用的输入输出设备开关量、数码管显示器、与输入输出相关的接口芯片及其驱动程序进行了详细的讲解。最后给出了一个具体的输入输出的应用,以此来了解如何进行一个完整的输入输出系统的设计。
(This paper mainly introduced the DVCC8086 16 bits miniature computers’ hardware compositions, discussed the relating contents of 16 bits microcomputers experiments system’s input and output. Described DVCC8086 16 bits miniature machines’s resources, simultaneously also include the input-output device switch quantity, the digital tube monitor, and the relating interface chips and its drivering program carried on the detailed explanation of the input and output. Finally produced a concrete input and output application. In this way to help to understand how to design a complete input and output system.)
