Note for Tables and : Address range is A18:A-1 in byte mode and A18:A0 in word mode. See Word/Byte Configura-
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 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 VID (11.5 V
to 12.5 V) on address pin A9. Address pins A6, A1, and A0 must be as shown in
Table 4, on page 16. In addition, when verifying sector protection, the sector ad-
dress must appear on the appropriate highest order address bits (see Table 2, on
dress 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 autose-
lect command via the command register, as shown in Table 5, on page 25. This
on using the autoselect mode.
