AD9834 initial phase

Hi everyone,

 

I would like to know if it is possible to set exactly the starting phase of AD9834 right after setting internal bit RESET to 0. As the technical datasheet explains, RESET bit/pin does not reset phase or frequency registers, and so as I have observed, AD9834 starts off at a random point, which is not important in frequency but it does with phase. Registers PHASE0 and PHASE1 are only useful when considered relatively to each other, but do not represent any absolute value.

 

Does anyone know how to achieve it?

Thank you!
