Hello,
to be honest, I believe if someone could help, it would happen and I do not see any point in creating more and more topics for same thing.
- How to unlock write protected registers in mbed? - Electronics and hardware - Arm Mbed OS support forum
- Sample code for Target Nuvoton m2351 for writing to registers - Mbed OS / Hello world! - Arm Mbed OS support forum
- plus this one
More useful can be created one topic and time to time publish your actual state (what you already tried or did). That will also hold the topic on the top of topic list and maybe sometimes someone will help you.
From my point of view that is more related to Nuvoton (Technical Community - Nuvoton) brcause it seems to be Nuvoton specific.
BR, Jan
