ValidateAuxData problem

[JukkaMlovuDes]

Hello! An error has occurred regarding ValidateAuxData. Some of the last 64 frames have a value of 0x7FFF.
For the first time, the value 0x7FFF is found on the 770 element of the "frame" array (the same as the 2nd element of the "data" array).
A total of 0x7FFF occurs 8 times. Are there any ways to solve this problem?

I also wanted to clarify what value should be in the configuration register at EEPROM 0x2403? Can I write my values to the configuration register? If I can, which ones and how do they affect?
