Temporary Sector Group Unprotect
This feature allows temporary unprotection of previously protected sector groups to change data
in-system. The Sector Group Unprotect mode is activated by setting the RESET# pin to
V
ID
. Dur-
ing this mode, formerly protected sector groups can be programmed or erased by selecting the
sector group addresses. Once V
ID
is removed from the RESET# pin, all the previously protected
sector groups are protected again. For this feature,
Figure 1
shows the algorithm, and
Figure 23
shows the timing diagrams.
Notes:
1.
All protected sector groups unprotected (If WP# = V
, the highest or lowest address sector
remains protected for uniform sector devices, the top or bottom two address sectors remains
protected for boot sector devices).
All previously protected sector groups are protected once again.
