Note:
The address range is A20:A-1 in byte mode (BYTE#=V
IL
) or A20:A0 in word mode (BYTE#=V
IH
).

Autoselect Mode
The autoselect mode provides manufacturer
and device identification, and sector protection
verification, through identifier codes output on
DQ7–DQ0. This mode is primarily intended for
programming equipment to automatically
match a device to be programmed with its cor-
responding programming algorithm. However,
the autoselect codes can also be accessed
in-system through the command register.
When using programming equipment, the au-
toselect mode requires V
ID
(11.5 V to 12.5 V)
on address pin A9. Address pins A6, A1, and A0
must be as shown in
Table 6, on page 16
. In
addition, when verifying sector protection, the
sector address must appear on the appropriate
highest order address bits (see
Table 2, on
page 13
through
Table 5, on page 16
).
Table 6,
on page 16
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 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
Table 14, on page 29
. This method does not re-
quire V
ID
. Refer to the
“Autoselect Command
Sequence” on page 25
section for more infor-
mation.
