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
Note: Identifier codes for manufacturer and device IDs exhibit odd parity with DQ7 defined as the parity bit.

been set as required, the programming equipment
may then read the corresponding identifier code on
