Is there more information available on the how the flash protection works on this part?
Specifically the different protection levels and how FEEHID and FEEPRO operate.
Yes, there is a gap in the released datasheet regarding the flash protection mechanism.
It will take time for this to be integrated into the released datasheet but, the details in this document are correct.
Once permanently protected only a Mass erase is recognized by the flash controller – there are no changes allowed to the FEEPRO register.
