Synchronising with DDS sweep mode

Hi,

 

I have configured DDS to work in sweep mode. My inputs will be start and stop frequency with step size (step interval may remain constant). I want to know whether it is possible to get any status from DDS when it reaches particular frequency(i.e. any predefined intermediate frequencies other than stop frequency). My requirement is to switch some filter banks when it reaches particular intermediate frequency.

DDS is interfaced with microcontroller. So I want some indication from DDS whether that sweep frequency has reached that particular intermediate frequency so that I can synchronize switching of filters with microcontroller.

 

Thanks and Regards

Sijo
