    Temporary Sector Group Unprotect
    (
    Note:
    In this device, a sector group consists of four adjacent
    sectors that are protected or unprotected at the same time
    (see
    Table 4
    )).
    This feature allows temporary unprotection of previ-
    ously protected sector groups to change data in-sys-
    tem. The Sector Group Unprotect mode is activated by
    setting the RESET# pin to V
    ID
    (8.5 V – 12.5 V). During
    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.
    Figure 1
    shows the algorithm, and
    Figure 22
    shows the timing diagrams, for this feature.
