Sector Group Protection and Unprotection
The hardware sector group protection feature disables both program and erase operations in any sector
group (see
feature re-enables both program and erase operations in previously protected sector groups. Sector group
protection/unprotection can be implemented via two methods.
Sector protection/unprotection requires V
system or via programming equipment.

sector group unprotect, all unprotected sector groups must first be protected prior to the first sector group
unprotect write cycle.
The device is shipped with all sector groups unprotected. Spansion offers the option of programming and
protecting sector groups at its factory prior to shipping the device through Spansion Programming Service.
Contact a Spansion representative for details.
It is possible to determine whether a sector group is protected or unprotected. See
