Autoselect Mode
The autoselect mode provides manufacturer and de-
vice identification, and sector group protection verifica-
tion, through identifier codes output on DQ7–DQ0.
This mode is primarily intended for programming
equipment to automatically match a device to be pro-
grammed with its corresponding programming algo-
rithm. However, the autoselect codes can also be
accessed in-system through the command register.
When using programming equipment, the autoselect
mode requires V
A9. Address pins A6, A1, and A0 must be as shown in
Table 3. In addition, when verifying sector group pro-
Note: Identifier codes for manufacturer and device IDs exhibit odd parity with DQ7 defined as the parity bit.

tection, the sector group address must appear on the
appropriate highest order address bits (see Table 4).
Table 3 also 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 Table 5. This method
does not require V
Autoselect Command Sequence section for more in-
formation.
