E2E英文论坛工程师问，具体问题是什么？

您可以将您的输入是什么？您要实现什么？具体的问题表现是什么？或您的疑惑是什么等，具体描述下吗？

Thank you for your reply. I've solved the problem mentioned earlier, it's my test device that's the problem. But I encountered a new problem, the auto mode in CLKin_SEL_MODE of LMK04828 PLL1 cannot be used.  When the clkin0 signal source is disconnected, the chip does not automatically switch to CLKin1 to start working.The picture below is my configuration picture：

This is my specific register configuration

I have modified the register as you said, but still can't achieve the switch function

I have fed your question back to the E2E engineer and when I get a response I will get back to you 

thanks

I haven't received a response so far, I've asked for progress and I'll be back here when I get any update
