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
ID
on address pin A9. Address pins
A6, A3, A2, A1, and A0 must be as shown in
Table 3
.
In addition, when verifying sector protection, the sector
address must appear on the appropriate highest order
address bits (see
Table 2
).
Table 3
shows the remain-
ing address bits that are don’t care. When all neces-
sary bits have been set as required, the programming
equipment may then read the corresponding 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 Tables
10
and
11
. This
method does not require V
ID
. Refer to the
Autoselect
Command Sequence
section for more information.
Table 3.
