Autoselect Mode
The autoselect mode provides manufacturer and de-
vice identification, and sector protection verification,
through identifier codes output on DQ7–DQ0. This
mode is primarily intended for programming equipment
to automatically match a device to be programmed with
its corresponding programming algorithm. However,
the autoselect codes can also be accessed in-system
through the command register.
When using programming equipment, the autoselect
mode requires VID (11.5 V to 12.5 V) on address pin
A9. Address pins A6, A1, and A0 must be as shown in
Autoselect Codes (High Voltage Method) table. In addi-
tion, when verifying sector protection, the sector ad-
dress must appear on the appropriate highest order
address bits. Refer to the corresponding Sector Ad-
dress Tables. The Command Definitions table shows
the remaining address bits that are don’t care. When all
necessary bits have been set as required, the program-
ming equipment may then read the corresponding
identifier code on DQ7–DQ0.
To access the autoselect codes in-system, the host
system can issue the autoselect command via the
command register, as shown in the Command Defini-
tions table. This method does not require VID. See
“Command Definitions” for details on using the autose-
lect mode.

Sector Group Protection/Unprotection
The hardware sector group protection feature dis-
ables both program and erase operations in any sec-
tor group. Each sector group consists of four adjacent
sectors. Table 4 shows how the sectors are grouped,
and the address range that each sector group con-
tains. The hardware sector group unprotection fea-
ture re-enables both program and erase operations in
previously protected sector groups.
Sector group protection/unprotection must be imple-
mented using programming equipment. The procedure
requires a high voltage (VID) on address pin A9 and the
control pins. Details on this method are provided in a
supplement, publication number 19613. Contact an
AMD representative to obtain a copy of the appropriate
document.
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 “Autoselect Mode” for
details.

Temporary Sector Group Unprotect
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 VID. During this mode,
formerly protected sector groups can be programmed
or erased by selecting the sector group addresses.
Once VID is removed from the RESET# pin, all the
previously protected sector groups are
protected again. Figure 1 shows the algorithm, and
the Temporary Sector Group Unprotect diagram (Fig-
ure 16) shows the timing waveforms, for this feature.
