    As a user,                   Learning new thing is challenging . In the case of this IC, i can see in version
12.60 of Xgecu software, and based in the image you post, that all 3 security registers LB1, LB2 or LB3, are set to 1,
then OTP (one time programming) seem activated and present in the IC.
AS i never worked with this one, but found that you have two entries a normal IC and an OTP version
version of the IC, that shows an 'ERASE OTP ' selection in the 'options' tab at bottom .
Reading the datasheet isn't conclusive for me if the OTP set can be fully reverted or not.

Hope it helps
