Hi all,

Hello, The command 0x25 VOUT_MARGIN_HIGH is not NVM backed. It will reset to 0x0000 at each power-on. This is mentioned in the product datasheet.

You should still be able to write to the command in volatile memory though. Does this work?

Hi Terry, I see. This appears to be a bug in our Fusion GUI software. It does not make sesne to read back these values after the Reset. I will follow up with the software developer about it. For now you may waive those lines. An update would be included in an upcoming version of Fusion.
