Autoselect
The Autoselect mode provides manufacturer ID, Device identification, and sector protection information,
through identifier codes output from the internal register (separate from the memory array) on DQ7-DQ0. This
mode is primarily intended for programming equipment to automatically match a device to be programmed
with its corresponding programming algorithm (see
in-system.
There are two methods to access autoselect codes. One uses the autoselect command, the other applies V
on address pin A9.
When using programming equipment, the autoselect mode requires V
