With the continuous development of single-chip microcomputer applications, there are more and more multi-chip systems composed of multiple single-chip microcomputer, and information exchange between multiple single-chip microcomputer is a whole. The work of a single-chip microcomputer is divided into multiple single-chip microcomputer. On the one hand, the performance of the system can be improved, and on the other hand, the hardware design of the system can be simplified.Asynchronous serial por
