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。-From 16 DVCC8086 introduce microcomputer hardware components began to discuss the experimental system microcomputer 16 input and output of relevant content. Descr iption DVCC8086 16 microcomputer itself all the resources, but also on the design used in the volume of input and output device switches, digital tube display, and input-output interface chip and its associated drivers carried out a detailed explanation. Finally given a specific input-output applications, in order to learn how to conduct a complete input-output system design.
