In my application I want to use AD9910 to generate LFM (frequency sweep from 300-310MHz) and Single tone 317MHz based on a square wave input 10KHz. For eg. 20us I need to generate ramp and 80us I need to generate tone.
For this I will be loading FTW for 317MHz in Profile0
and set DRG limit registers for 300 and 310 MHz and all required parameters for ramp generation.
My doubt is how can I toggle between RAMP and TONE.
Can I change CFR2 which is digital ramp enable/disable periodically to do this.
Please give some suggestions on this
