Autoselect Mode
The autoselect mode provides manufacturer and de-
vice identification, and sector protection verification,
through identifier codes output on DQ7–DQ0. This
mode is primarily intended for programming equip-
ment to automatically match a device to be pro-
grammed 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
Legend: T = Top Boot Block, B = Bottom Boot Block, L = Logic Low = V
Don’t care.

Table 7. In addition, when verifying sector protection,
the sector address must appear on the appropriate
highest order address bits (see Tables 3–6). Table 7
shows the remaining address bits that are don’t care.
When all necessary bits have been set as required,
the programming equipment may then read the corre-
sponding identifier code on DQ7–DQ0.
To access the autoselect codes in-system, the host
system can issue the autoselect command via the
command register, as shown in Table 14. This method
does not require V
