Autoselect Mode
The autoselect mode provides manufacturer and
device 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 V
ID
on address pin A9. Address pins A6,
A1, and A0 must be as shown in Autoselect Codes
(High Voltage Method) table. In addition, when veri-
fying sector protection, the sector address must appear
on the appropriate highest order address bits. Refer to
the corresponding Sector Address 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 programming
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 V
ID
. See
“Command Definitions” for details on using the autose-
lect mode.

Sector Protection/Unprotection
The hardware sector protection feature disables both
program and erase operations in any sector. The hard-
ware sector unprotection feature re-enables both
program and erase operations in previously protected
sectors.
