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
Address pins A6, A1, and A0 must be as shown in
sector address must appear on the appropriate highest order address bits (see

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
