Autoselect Mode
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
A1, and A0 must be as shown in
when verifying sector protection, the sector address
L = Logic Low = V
Note: Outputs for data bits DQ8–DQ15 are for BYTE#=V
