AD2S1210 Interface Issues

I am attempting to read resolver postion with an AD2S1210 and have the following issues:

1) When in config mode, the MS bit is always set, indicating a config parity fault.  However, the config parity error bit in the fault register is not set and when I read registers they return the data that was stored (plus the MS bit set)

 

2) I am reading position data in normal mode.  The data goes from 0-180 deg twice instead of 0-360 deg.  I have observed the raw data and the MS bit in this mode is never set.

 

Any ideas?

 

Thanks.
