I am trying to read output from my board with an AD9649 ADC. I can read the ID and Grade, and I can write and readback all of the memory registers, but I don't see the data correctly. I want to run a test such as when setting reg 0x0D, but the bits do not change. The datasheet is quite confusing in places, like the BIST section, and the OR/MODE settings. I never see the DCO clock run, I don't know how to turn it on. What are the default register settings I should use to run the 0x0D test, and similarly what are the default settings to readback the analog input data?
