The hardware sector group protection feature disables both program and erase
operations in any sector group (see
group unprotection feature re-enables both program and erase operations in pre-
viously protected sector groups. Sector group protection/unprotection can be
implemented via two methods.
Sector protection/unprotection requires V
implemented either in-system or via programming equipment.
the algorithms and
dard microprocessor bus cycle timing. For 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 op-
tion of programming and protecting sector groups at its factory prior to shipping
the device through Spansion Programming Service. Contact a Spansion represen-
tative for details.
It is possible to determine whether a sector group is protected or unprotected.
