Sector protection and unprotection requires V
ID
on the RESET# pin only, and can
be implemented either in-system or via programming equipment.
Figure 2
shows
the algorithms and
Figure 23
shows the timing diagram. This method uses stan-
dard microprocessor bus cycle timing. For sector unprotect, all unprotected
sectors must first be protected prior to the first sector unprotect write cycle.
Temporary Sector Unprotect
This feature allows temporary unprotection of previously protected sectors to
change data in-system. The Sector Unprotect mode is activated by setting the
RESET# pin to V
ID
. During this mode, formerly protected sectors can be pro-
grammed or erased by selecting the sector addresses. Once V
ID
is removed from
the RESET# pin, all the previously protected sectors are protected again.
Figure
shows the algorithm, and
Figure 22
shows the timing diagrams, for this feature.
Notes:
1. All protected sectors unprotected.
2. All previously protected sectors are protected once again.
