Sector Group Protection and Unprotection
The hardware sector group protection feature disables both program and erase operations in any sector
group (see
Table 7.11 on page 38
to
Table 7.22 on page 45
). The hardware sector group unprotection
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
ID
on the RESET# pin only, and can be implemented either in-
system or via programming equipment.
Figure 7.2 on page 46
shows the algorithms and
Figure 16.13
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 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
Autoselect Mode
on page 40
for details.
