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-
m e n t t o a u t o m a t i c a l l y m a t c h a d ev i c e t o b e
programmed with its corresponding programming al-
gorithm. 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
Sector Address, X = 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
