Autoselect Mode
The autoselect mode provides manufacturer and device identification, and sector group protection verification,
through identifier codes output on DQ7–DQ0. This mode is primarily intended for programming equipment to au-
tomatically 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 on address pin A9. Address pins A6, A3,
A2, A1, and A0 must be as shown in
Table 18 on page 80. In addition, when verifying sector protection, the sector
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
