Sector Group Protection and
Unprotection
The hardware sector group protection feature disables
both program and erase operations in any sector
group. In this device, a sector group consists of four
adjacent sectors that are protected or unprotected at
the same time (see
Table 4
). The hardware sector
group unprotection feature re-enables both program
and erase operations in previously protected sector
groups. Sector group protection/unprotection can be
implemented via two methods.
Sector protection/unprotection requires V
ID
on the RE-
SET# pin only, and can be implemented either in-sys-
tem or via programming equipment. Figure 2 shows
the algorithms and Figure 24 shows the timing dia-
gram. This method uses standard microprocessor bus
cycle timing. For sector group unprotect, all unpro-
tected sector groups must first be protected prior to
the first sector group unprotect write cycle.
The device is shipped with all sector groups unpro-
tected. AMD offers the option of programming and pro-
tecting sector groups at its factory prior to shipping the
device through AMD’s ExpressFlash Service. Con-
tact an AMD representative for details.
It is possible to determine whether a sector group is
protected or unprotected. See the
Autoselect Mode
section for details.
