Clock time is the key issue of a second, because the second is the smallest unit of the clock, but the use of 80 C51 timer / counter for timing, that is, by working methods 1, the largest of its regular time can only reach 131 ms, worse from one second Very far away. Therefore, the second time with regular hardware and software integration of the counting method, such as the timing of the timer is set to 125 ms, this overflow eight counts can be 1 s, and eight counts can use the software method. The use of interruption, that is interrupted by service procedures counter the cumulative number of overflow, or get full eight seconds time. Then through the process of accumulation and numerical value compared to achieve
