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
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

The Write Protect function provides a hardware method of protecting without
using V

erase functions in sectors 0, 1, 140, and 141, independently of whether those
sectors were protected or unprotected using the method described in “Sector/
Sector Block Protection and Unprotection”.
If the system asserts V
tors 0, 1, 140, and 141 were last set to be protected or unprotected. That is,
sector protection or unprotection for these sectors depends on whether they were
last protected or unprotected using the method described in “Sector/Sector Block
Protection and Unprotection”.
