protected sector groups. Sector group protection/unprotection can be imple-
mented via two methods.
Sector protection/unprotection 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 24 shows the timing diagram. This method uses stan-
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.
See the Autoselect Mode section for details.
