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 16.11 on page 82 shows the timing diagrams, for this feature.
Figure 7.1 Temporary Sector Group Unprotect Operation
Notes
1. All protected sector groups unprotected (If WP# = VIL, the highest or lowest address sector remains protected for uniform sector devices;
the top or bottom two address sectors remains protected for boot sector devices).
2. All previously protected sector groups are protected once again.
