Sector Group Protection and Unprotection
The hardware sector group protection feature disables both program and erase
operations in any sector group (see Tables 14 – 25). The hardware sector group
unprotection feature re-enables both program and erase operations in previously
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, on page
44 shows the algorithms and Figure 24, on page 86 shows the timing diagram.
This method uses standard 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 repre-
sentative for details.
It is possible to determine whether a sector group is protected or unprotected.
