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 1 shows the algorithm, and Figure 21, on page 35 shows the timing  
diagrams, for this feature.
