基于赛思伟福实验仪上的8259外部中断代码.用8088/86控制8259可编程中断控制器,实现对外部中断的响应和处理.要求程序中对每次中断进行计数,并将计数结果显示在LED数码管上.-Steamboat Fu experimental apparatus based on race on the 8259 external interrupt source. With the 8088/86 Control 8259 programmable interrupt controller, to realize the external interrupt response and handling. Require procedures for each interrupt count, and count the results of displayed in the LED digital tubes.
