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 17.11 on page 46 shows the timing diagrams, for this feature.

Notes

2. All previously protected sectors are protected once again.
