7.11
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.
