It is possible to determine whether a sector is protected or unprotected. See
“Au-
toselect Mode” on page 15
for details.
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, on
page 17
shows the algorithms and
Figure 23, on page 50
shows the timing dia-
gram. This method uses standard 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
2, on page 17
shows the algorithm, and
Figure 22, on page 49
shows the timing
diagrams, for this feature.
Notes:
1. All protected sectors unprotected.
2. All previously protected sectors are protected once again.
