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 program-
ming algorithm. However, the autoselect codes can also be
accessed in-system through the command register.
When using programming equipment, the autoselect mode
requires V
