LMX2492EVM: Assistance Needed with Configuring Start Frequency

Part Number: LMX2492EVM

Tool/software:

Hi TI team,

I am currently working on a project involving the LMX2492EVM and have encountered some issues.
I am developing my own C++ GUI to interface with the device and control its operation according to my requirements.

At this stage, I am able to successfully configure and apply frequency ramps that start at 2400 MHz and end at a frequency of my choice by writing to the relevant registers.
However, when attempting to configure a different start frequency, the system fails to update as expected. I have tried modifying various registers that seemed logically related to the start frequency, but without success.

So far, I have used the following registers for ramp configuration: 86, 87, 88, 93, 94, 95, 96, 16, and 17.
Additionally, I considered modifying registers 19, 20, and 21, but they did not lead to the desired outcome.

I have been following the attached reference files for guidance, but I may have missed some key aspects.
I would greatly appreciate your help in clarifying which registers specifically need to be adjusted to successfully change the start frequency.

Thank you very much for your support!
