Sector Protect/Sector Unprotect requires VID on the RESET# pin only, and can be implemented either in-
system or via programming equipment. Figure 8.2 on page 26 shows the algorithms and Figure 17.13
on page 56 shows the timing diagram. For sector unprotect, all unprotected sectors must first be protected
prior to the first sector unprotect write cycle. Note that the sector unprotect algorithm unprotects all sectors in
parallel. All previously protected sectors must be individually re-protected. To change data in protected
sectors efficiently, the temporary sector unprotect function is available. See Temporary Sector Unprotect
The device is shipped with all sectors unprotected. Optional Spansion programming service enable
programming and protecting sectors at the factory prior to shipping the device. Contact your local sales office
for details.
It is possible to determine whether a sector is protected or unprotected. See Autoselect Mode on page 22 for
details.
