Can the security setting info change to enable from prohibit?

Latest Updated:03/16/2017


I have set the security information at "Chip erase enable flag" and "Boot block cluster write enable flag" with the self-programming.
Can these setting of the security information be changed to "enable" from "prohibit"?


No, it is impossible. See below:
