AD5933 / AD5934 stuck in program-flow, DFT does not complete

I have a AD5934 connected to a microcontroller via i2c. Running at 3.3V the SCL and SDA are pulled up using 4.7kOhm resistors.

 

During the software flow referenced in the datasheet, the program often gets stuck waiting for DFT to complete. I have tried arbitrary delays, running reference and online code directly, all show the same issues.
