Table 7. S29JL032H Sector/Sector Block Addresses for Protection/Unprotection (Bottom Boot Devices)
Sector protect/Sector Unprotect requires VID on the RESET# pin only, and can be
implemented either in-system or via programming equipment. Figure 2 shows
the algorithms and Figure 25 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 par-
allel. All previously protected sectors must be individually re-protected. To
change data in protected sectors efficiently, the temporary sector unprotect func-
tion is available. See “Temporary Sector Unprotect” .
The device is shipped with all sectors unprotected. Optional Spansion program-
ming 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 the
Autoselect Mode section for details.
