Reset command is
required to return to read mode

Sector Group Protection & Unprotection
The hardware sector group protection feature disables both program and erase operations in any sector
group. The hardware chip unprotection feature re-enables both program and erase operations in previously
protected sector group. A
sector group
consists of
four adjacent sectors
that would be protected at the
same time. Please see Table 2 which show the organization of sector groups.
There are two methods to enable this hardware protection circuitry. The first one requires only that the
RESET# pin be at V
ID
and then standard microprocessor timings can be used to enable or disable this
feature. See Flowchart 6a and 6b for the algorithm and Figure 11 for the timings.
When doing Sector Group Unprotect, all the unprotected sector groups must be protected prior to any
unprotect write cycle.
The second method is for programming equipment. This method requires V
ID
to be applied to both OE#
and A9 pins and non-standard microprocessor timings are used. This method is described in a
separate document, the Datasheet Supplement of EN29LV640H/L ; EN29LV640U, which can be
obtained by contacting a representative of Eon Silicon Solution, Inc.
