    Hi Kailyn,

    There is a series of videos on the PGA308EVM landing page that show the detailed instructions on how to program the PGA308EVM and showing the complete calibration process, I recommend reviewing the complete video series:

    https://www.ti.com/tool/PGA308EVM

    Video Part 2, provides detailed instructions on how to program the OTP, and how to program RAM memory.

    Programming the OTP registers is normally done after calibration is complete.  A valid configuration has to be loaded in the PGA308 RAM first, then follow the process, with step 1 read the RAM contents prior programming OTPs as shown below:

    Thank you and Regards,
