另外最重要的是会汇编的两条指令：mov与jmp。【delay子程序】：DELAY:;延时100ms子程序MOVR7,*200;500us*200=100msDLY0:MOVR6,*250;2us*250=500usDJNZR6,$DJNZR7,DLY0DJNZACC,DELAY;200ms*ACCRET这段程序实现延时100ms的功能，它是基于“DJNZR6,$〞这条指令执行时间为2us这个根底之上的。使用两层循环，将此句话执行：250*200=50000次，也就是100000us，换算成ms为100ms。四、实验代码ORG0000HMOVSP,*60H;/*送堆栈首址*//*第一种全亮再全灭*/MAIN0:MOVR0,*2MOVP1,*00HMOVA,*2ACALLDELAYCASE0:
