About the code security on BF50XF

     In BF50XF datasheet, it is said as:


• 128-bit user programmable OTP cells

• 64-bit unique device number



Need to check with if this  device number is unique per CHIP, which means that each chip will has an exclusive device number.


I thought maybe this unique device number could generate the OTP number by some algorithm designed by user, and the code could check the OTP run-timely. Or you may have some better method to increase the security of code in on-chip FLASH in BF50XF.
