| 摘 要： | 使用不同频率的收发时钟和不同波特率，分别控制8251A电路进行同步或异步串行数据通信。实验结果表明：8251A电路的工作时钟CLK与收发时钟RxC(TxC)在频率数值上没有严格的制约关系，有效异步通信波特率可以数倍于19.2kbps。本实验结果为有效提高8251A串行通信接口电路的通信传输效能提供了可靠的实验数据。

| Abstract: | A serial interface circuit's synchronous or asynchronou s serial da ta communication is respectively controlled by using RxC (TxC) with different fr equency and different baud rate. The measurement results showed the frequency b e tween 8251A interface circuit's CLK pulse and RxC (TxC) pulse have loose limit r elationship; asynchronous available communication baud rate some times higher th an 19.2 kbps. The measurement results provide reliable experiment data for 82 51A serial interface circuit' communication transmission ability is reasonable and p roper enhanced. |
