Autoselect Mode
The autoselect mode provides manufacturer and device identification, and sector group pro-
tection 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 corresponding programming algorithm. However, the autoselect codes can also be ac-
cessed in-system through the command register.
When using programming equipment, the autoselect mode requires VID on address pin A9.
Address pins A6, A3, A2, A1, and A0 must be as shown in
Table 5 on page 37
. In addition,
when verifying sector protection, the sector address must appear on the appropriate highest
order address bits (see
Table 2 on page 16
).
Table 5 on page 37
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 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 12 on page 63
and
Table 14 on page 65
. This
method does not require V
ID
. Refer to the
“Autoselect Command Sequence” section on page
51
for more information.
