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 programming equipment to automatically match a
device to be programmed with its corresponding programming algorithm. How-
ever, the autoselect codes can also be accessed in-system through the command
register.
When using programming equipment, the autoselect mode requires VID on ad-
dress pin A9. Address pins A6, A3, A2, A1, and A0 must be as shown in
In addition, when verifying sector protection, the sector address must appear on
the appropriate highest order address bits (see
maining address bits that are don’t care. When all necessary bits have been set
as required, the programming equipment may then read the corresponding iden-
tifier 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
not require V
information.
