The other way, is to tell the 9250 to continually read the 6 data registers of the magnetic device itself, and copy the data into 6 of the spare registers on the 9250, and then you just read the data from those 6 spare registers on the 9250. It was a problem to get this to work, but once I got it working, it worked just fine. I guess this scheme is not the "serial interface bypass".
I am still dealing with this issue. I am trying what you suggested and still getting do response from it. You mentioned you had issues with getting this working . Would you mind posting the code you used to set this up? I would really appreciate it.
