Temporary Sector Unprotect
This feature allows temporary unprotection of previously protected sectors to change data in-system. The
Sector Unprotect mode is activated by setting the RESET# pin to VID. During this mode, formerly protected
sectors can be programmed or erased by selecting the sector addresses. Once VID is removed from the
RESET# pin, all the previously protected sectors are protected again.
Figure 7.1 shows the algorithm, and Figure 15.11 on page 42 shows the timing diagrams, for this feature.

Notes
1. All protected sectors unprotected.
2. All previously protected sectors are protected once again.
