HMC7043 SYSREF FSM State Question

I am following the "Typical programming sequence" in the HMC7043 datasheet.  I complete step 7 (toggle the restart dividers/fsms bit).  Before I do step 8, I am checking if the SYSREF FSM state has reached a value of 2 (done).  However, the SYSREF FSM state is remaining in state 0 (reset).  Do you have any suggestions for what I might be doing wrong or why the SYSREF FSM state is remaining in state 0?

 

Thanks once again for any help you can provide!
