Solved! Go to Solution.
You don't need to write any code, just modify these areas.
for example:Enable system security and Enable mass erase.
__FlashConfig
DCD 0xFFFFFFFF ; 8 bytes backdoor comparison key
DCD 0xFFFFFFFF ;
DCD 0xFFFFFFFF ; 4 bytes program flash protection bytes
DCD 0xFFFF7FFF ; FDPROT:FEPROT:FOPT:FSEC(0xFE = unsecured)
__FlashConfig_End
please refers to this article.

It is very similar to the security features of the Kinetis family MCUs. You can refer to AN4507 Using the Kinetis Security and Flash Protection Features
