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

Sector Unprotect mode is activated by setting the RE-

SET# pin to VID. During this mode, formerly protected

sectors can be programmed or erased by selecting the

sector addresses. Once V

ID is removed from the RE-

SET# pin, all the previously protected sectors are

protected again. Figure 1 shows the algorithm, and

Figure 26 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 Temporary sector

Unprotect mode.

Notes:

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

IL,

sectors 0, 1, 140, and 141 will remain protected).

2. All previously protected sectors are protected once

again.
