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 cor-
responding programming algorithm. However,
the autoselect codes can also be accessed
in-system through the command register.
When using programming equipment, the au-
toselect mode requires V
on address pin A9. Address pins A6, A1, and A0
must be as shown in
addition, when verifying sector protection, the
Legend: T = Top Boot Block, B = Bottom Boot Block, L = Logic Low = V
Address, X = Don’t care.
