编写一个延时1MS子程序根据题目选择是定时还是记数状态，本题选择记数状态。然后根据延时1MS计算出计时器的初值是E0H（高8位）18H（低5位）。最后编写算法，对T0初始化，利用T0的中断TF0调用中断处理程序。-prepared a delay rungs subroutine under the topic chosen is not a time to memorize numbers or state of mind of the few options that state. According to delay timer rungs calculate the initial value is E0H (high 8) 18H (Low 5). Preparation of the final algorithm, the T0 initialization, interrupt the use of T0 TF0 call interrupt handling procedures.
