Autoselect Mode
The autoselect mode provides manufacturer and device identification, and sector group protection
verification, through identifier codes output on DQ7–DQ0. This mode is primarily intended for pro-
gramming equipment to 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
ID
on address pin A9. Ad-
dress pins A6, A3, A2, A1, and A0 must be as shown in
Table 17
. In addition, when verifying sector
protection, the sector address must appear on the appropriate highest order address bits (see
Table 6
through
Table 16
).
Table 17
shows the remaining address bits that are don’t care. When
all necessary bits are 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 34
and
Table 35
. This method does not require V
ID
. See
Autoselect Command Sequence
for more information.
Legend:
L = Logic Low = V
IL
, H = Logic High = V
IH
, SA = Sector Address, X = Don’t care.
