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.)
