AD7762 reading Status register and others

I have been troubleshooting my the AD7762 for while and I can't figure out how to read the status register (or any register). I can configure the chip and program a filter in it. But I can't read any register. I must say the documentation is really hazy on the reading procedure for the registry.

 

I have a few example of procedure and the results in a timing diagram, there is a lot of time between each steps(~5 sec) but they are all executed.

Reset_PF_RR: reset, Program filter and read status (Power off)

Reset_Pon_PF_RR: reset, Power On, Program filter and read status

Reset_Pon_RR: reset, Power On, read status

Reset_RR: reset, Power On, read status

 

Am I the only one struggling with this. Does anyone has a succefull procedure for reading the registry? Can you share the timing diagram?
