The blocks are protected in groups, refer to Protection Groups. Once protected, Program and Erase operations within the protected group fail to change the data. There are three techniques that can be used to control Block Protection, these are the Programmer technique, the In-System technique and Temporary Unprotection. Temporary Unprotection is controlled by the Reset/Block Temporary Unprotection pin, RP ...
