| Abstract: | This paper expounds the structure of 89C51 serial communication port and calculation method of baud rate, it points out the 89C52 the two ways of baud rate based on 89C52 serial communication baud rate generator structure analysis. The corre-sponding relation of baud rate from 89C51＆89C52 and initial value is by calculated, and it find out the maximum of baud rate, and it presents the example of initialization programming. |
