80C196KC单片机系统的存储器扩展研究

Study on Memory Expansion of 80C196KC Microcontroller System

在分析80C196KC单片机存储器空间分配和4种总线控制方式的基础上,对控制信号线INST的应用进行详细地剖析。讨论了利用INST脚扩展存储器的方法,并给出相应扩展方法的地址定位表及控制电路。

Based on the analysis of the allocation of memory and four bus-control mode of 80C196KC single chip microcomputer, It exploits the behaviors of INST pin in detail and discusses the method using INST pin on expansion of the memories. At last, it offers according address table and control circuit.
