Hello, 

It is expected behavior, the marked registers below can be changed in the next "power on" only once it is set. 

Meanwhile, I got feedback from the development team. The issue with GUI will be fixed in the next version.

Hello, 

Thanks for pointing out the issue. 

We have raised an internal request for the same. 
Meanwhile, Can you please measure VCC3 when you uncheck the box? Is it same output voltage as VCC1

Hi, 

    Yes,Same as VCC1,Maybe the register mapping is right but description is wrong, and also VCC3 voltage configuration is valid for one time only after device power up.
