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 and unprotection requires V
ID
on the
RESET# pin only, and can be implemented either
in-system or via programming equipment.
Figure 2
shows the algorithms and
Figure 22
shows the timing
diagram. 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
protecting sector groups at its factory prior to shipping
the device through AMD
’
s ExpressFlash
Service.
Contact 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.

Note:
All sector groups are 256 Kbytes in size.
