AD9910 Write directly FTW / ASF register?

Hello...

 

As a test, I wanted to write directly the FTW and ASF registers to generate an output signal?

Is there any restriction whay I can not do that in this way? I have no signal at the output.

I have checked and SYS_CLK is at the right value, and have read back the resgisters and those have the intended value, but it seems it doesnt make any effect.

 

In my application, I need to enter an OFFSET frequency (via serial), and then a certain pattern will be output using the parallel port.

 

Thanks in advance for your help.
