7.11
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 VID. During this mode, formerly
protected sector groups can be programmed or erased by selecting the sector group addresses. Once VID is
removed from the RESET# pin, all the previously protected sector groups are protected again. Figure 7.1
shows the algorithm, and Figure 17.11 on page 51 shows the timing diagrams, for this feature.
