Maitry, I think this would require modifying the FPGA code. You could expose the "user regs" to read/write to a serial peripheral which you would have to add to the FPGA. This feature (the user i/o regs) is only present in the newest version of UHD (3.14), so you will have to build UHD from the master branch as well as rebuild the FPGA.

You should think about ways to make this work before modifying the FPGA. -- Martin K.
