Temporary Sector Group Unprotect
This feature allows temporary unprotection of previously protected sector groups to change data in-system.
The Sector Group Unprotect mode is activated by setting the RESET# pin to V
protected sector groups can be programmed or erased by selecting the sector addresses. Once V
removed from the RESET# pin, all the previously protected sector groups are protected again.
