| Abstract: | Taking 8031 single chip microcomputer as an example, the method of connection between 8251A programmmable serial communication interface and the single chip microcomputer is introduced. The highlight of this method is the standard baud rate flexible selection of the serial communication and the serial communication interruption programming is explained though an example. |
