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 automatically match
a device to be programmed with its corresponding programming algorithm.
However, the autoselect codes can also be accessed in-system through the com-
mand register.
When using programming equipment, the autoselect mode requires VID on ad-
dress pin A9. Address pins A6, A3, A2, A1, and A0 must be as shown in
Table 15on page 38. In addition, when verifying sector protection, the sector address
must appear on the appropriate highest order address bits (see
Table 7-TableWhen all necessary bits are 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 autose-
Command Sequence section for more information.
