Dear NXP  Engineers

      I set the baud rate according to the datasheet (9600 bit/s,$33), but the actual interval is 54us-48us. unstable. Are there other registers that need to be set?

HI

精度的话主要是两点要明白:

1: 晶振频率本身就有个误差这个是无法避免的。

2:计算公司自带一个误差也是无法避免的

这个应该和晶振什么的没关系,问题只会出现在配置单峰,且要使用NRZ和433发送(这样就会出现发送数据不稳定)。如下图所示:
