I'm recently using AD9162, trying to synchronize the output phase of MAIN nco between multiple chips, and confronted by serval problems which i think is not clearly descripted in the datasheet.

I tried to use the register bit FTW_LOAD_SYSREF(register 0x113 bit2), which is supposed to reset NCOs at the same time. 

But it seems never worked and the acknowledge bit FTW_LOAD_ACK never went high, which makes very sad and have no way about it.

The above is my major problem.
