The autoselect mode provides manufacturer and device
identification, and sector protection verification, through
identifier codes output on I/O
primarily
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
Address pins A6, A1, and A0 must be as shown in

addition, when verifying sector protection, the sector
address must appear on the appropriate highest order
address bits. Refer to the corresponding Sector Address
Tables. The Command Definitions table shows the
remaining address bits that are don't care. When all
necessary bits have been set as required, the
programming
corresponding identifier code on I/O
autoselect codes in-system, the host system can issue
the autoselect command via the command register, as
shown in the Command Definitions table. This method
does not require V
