Hi,

 

I have a question about AD9914's direct mode usage:

 

Is there any function of P2:P0 pins situation for direct mode?

 

Maybe frequency, amp or phase words can be writen into the related profile mode fr/amp/ph registers and inside the DDS they can be driven over these registers.

 

So, pls follow the below scenario:

We apply P2:P0: "000"

Then use DDS at direct mode.

At some time intervals, we check DDS's profile registers by writing & reading default datas on these registers.

If we detect for ex. profile-1's registers have a problem. Then we can continue to use profile-2 by setting P2:P0 as "001"

This can give us an option.

(Sure this is not a preferred condition, but only an option.)

 

Best regards,

Sercan
