ad9914 Direct parallel programming

Hello Engineer Zone community 
It is my first post here so i hope every thing will go fine. Am using ad9910 DDS evaluation kit, i want to generating a single freq using DIRECT PARALLEL PROGRAMMING using external MCU.

I have made the following steps but no success:
1-Set function pins into 0100
2-reset registers into their initial value by applying a pulse on master_reset pin
3-sending the 32 bit of tuning word 
4-applying a io_update signal 

did i miss any thing?

regards
Hosam



any help?

    Hi Hosam,

    Apologies for this thread was overlooked. You can check out this document for the basic things to be checked when using the DDS evaluation board via external control.

    Best regards,
