CDCE906: want to maintain the reprogrammed data.

Hello. 

I have investigated the CDCE906 on TIDA-00080. 

After I successfully re-programmed the data on CDCE906, I turned off the power and turned on again. 

Then I realized that CDCE906 had been restored to the factory setting.

So. I reprogrammed it again, and did the same thing, whenever I turn off-on, it is restored. 

The datasheet said. it is non-volatile memory so it can maintain the data that I programmed I think. 

Could you help me to find a way to maintain the data I programmed? 

Thank you. 

Regards.
