波特率的确定工具

对方式0来说，波特率已固定成fosc／12，随着外部晶振的频率不同，波特率亦不相同。常用的fosc有12MHz和6MHz，所以波特率相应为1000×103和500×103位／s。在此方式下，数据将自动地按固定的波特率发送／接收，完全不用设置-Baud rate to determine tool

On the way 0, the baud rate has been fixed into fosc/12, with the external crystal frequency of different baud rate is not the same. Common fosc has 12MHz and 6MHz, so the baud rate corresponding to 1000 × 103 and 500 × 103 位/s. In this mode, the data will be fixed baud rate automatically send/receive
