AD9910's output pins aren't responding

I am a student with no experience in programming, and my project consists in controlling this DDS (AD9910) with a MBED microcontroller. I have successfully established the communication between the AD9910 and the mbed's microcontroller (I can enable or disable the SYNC_CLK output through the Mbed), but I still don't have an output in the J3 (UNFILTERED IOUT) or the J4 (FILTERED IOUT) pins I have tried to modify the three Control Function Registers and the profile registers, but it has not worked.
 

PS: I have tried to obtain the output in the Single Tone and the RAM modes selecting the profiles through the Profile pins (P [0 ..2]) at the U6 header.

 

Thanks,

Vinicius
