Sampling ADC data

I'm trying to get data from an ADC7689,  using SPI. I have a NUCLEO STM31F411RE and the code is running on SW4STM32.

My problem is that when I send addresses, all I get is 0xFF, instead of the values the ADC converts.

What could be the cause of this problem? I'm pretty sure the configuration of the registers is correct.
