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-
men t t o aut o m at i c al ly ma tc h a de v i c e t o be
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
ID (9.0 V to 11.0 V) on address pin A9.
Address pins A6, A1, and A0 must be as shown in
Table 7. In addition, when verifying sector protection,
the sector address must appear on the appropriate
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
ID. Refer to the Autoselect Com-
mand Sequence section for more information.
Table 7.
