I am trying to verify what I write to the Mode register by reading it back. However, I'm getting inconsistent results. Is there a minimum time from removing CS of the write before reasserting it for the read?

 

I am seeing similar bahaviour for both the AD7790 and the AD7799.

 

Just a note: I have added the reset sequence of 32 1's before writing the command to the communications register.
