I can't vouch for the custom hard coding you're doing, as I don't have a way to verify everything will be set correctly since I'm not familiar with this way of doing thing, so take my reply with a grain of salt. But I assume you are if you've opted custom drivers instead of our SDK and solution.

But yes, from the radio test sample, you can:

Set the protection registers to enable R/W accress, (params being 0x100 0x50FA50FA)
Reboot (power cycle) the device.
Update the OTP memory registers
Set the OTP memory to a protected state with the params 0x100 0x00000000.

So yes, the description and order of operations you describe seems correct.

Best regards,

Simon
