]本文介绍了如何利用CPLD(复杂可编程逻辑器件)与单片机的结合实现并行I／ O(输入／输出)接口的扩展。该设计与用8255做并行I／O接口相比，与单片机软件完全兼容， 同时拥有速度快，功耗低，价格便宜，使用灵活等特点-] This article describes how to use the CPLD (complex programmable logic device) and the single-chip combination to achieve parallel I/O (input/output) interface expansion. The design and use 8255 to do parallel I/O interface as compared with the single-chip software is fully compatible at the same time have a fast, low power consumption and cheaper prices, the use of flexible features such as
