介绍了一种在不增加地址线的前提下实现MCS-51单片机外部程序存储器超大容量扩展的方法,并给出了在超64KB程序存储空间进行长跳转、子程序长调用和中断服务的通用编程模式。
This paper introduces a method to realize large capacity expansion of external program memory of MCS-51 without increasing the address lines, and gives a general description of long jump, subroutine call and interrupt service in the ultra-64KB program memory space Programming mode
