If the system asserts V
IH
on the WP#/ACC pin, the de-
vice reverts to whether sectors 0, 1, 140, and 141
were last set to be protected or unprotected. That is,
sector protection or unprotection for these sectors de-
pends on whether they were last protected or unpro-
tected using the method described in “Sector/Sector
Block Protection and Unprotection”.
Note that the WP#/ACC pin must not be left floating or
unconnected; inconsistent behavior of the device may
result.
Table 7.
WP#/ACC Modes
Temporary Sector Unprotect
(Note: For the following discussion, the term “sector”
applies to both sectors and sector blocks. A sector
block consists of two or more adjacent sectors that are
protected or unprotected at the same time (see Table
6).
This feature allows temporary unprotection of previ-
ously protected sectors to change data in-system. The
Temporary Sector Unprotect mode is activated by set-
ting the RESET# pin to
V
ID
. During this mode, formerly
protected sectors can be programmed or erased by
selecting the sector addresses. Once V
ID
is removed
from the RESET# pin, all the previously protected sec-
tors are protected again. Figure 1 shows the algo-
rithm, and Figure 25 shows the timing diagrams, for
this feature. If the WP#/ACC pin is at V
IL
, sectors 0, 1,
140, and 141 will remain protected during the Tempo-
rary sector Unprotect mode.

Notes:
1. All protected sectors unprotected (If WP#/ACC = V

,
sectors 0, 1, 140, and 141 will remain protected).
2. All previously protected sectors are protected once
again.
