首先,分别对8255、8253进行初始化,设置8255为A口、C口输出,设置8253的计数器0为工作模式3;其次,设置IRQ7的中断矢量,使得有IRQ7中断时调用SERVER;再次,调用INIT对计数值初始化;最后,主程序循环等待中断,开始秒表的计时。 2、 INIT子程序-First, the 8255,8253 initialization, set for the 8255 A-C mouth output, set 8253 as the Counter mode 0 3; Second, set up the interruption vector there, make it there interruption call SERVER; Again, call curl_setopt early to count before; Finally, the cycle of waiting for the main program interruption began stopwatch time. 2, curl_setopt Subroutine

秒表汇编程序主要实现汇编语言下面的电子钟功能.提供主要的设置时间,设置闹铃,显示时间等功能 下面是程序,已经在MASM5下编译运行通过..但有个缺点,也是明显的,就是CPU占用率太多.日后有时间再更正好了. -stopwatch assembler main language compilation of the following functional electronic bell. Provide the main setup time, Alarms installed show that the function is the following procedures have been compiled under the MASM5 running through .. There is a drawback also clear is that too many CPU utilization. future time to a more precisely.
