autoselect codes can also be accessed in-system through the command register.
When using programming equipment, the autoselect mode requires V
to 12.5 V) on address pin A9. Address pins A6, A1, and A0 must be as shown in
Table 4. In addition, when verifying sector protection, the sector address must
appear on the appropriate highest order address bits (see Tables

have been set as required, the programming equipment may then read the cor-
responding 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 Tables 10–11. This method
does not require V
lect mode.
The hardware sector protection feature disables both program and erase opera-
tions in any sector. The hardware sector unprotection feature re-enables both
program and erase operations in previously protected sectors.
The device is normally shipped with all sectors unprotected. However, the Ex-
pressFlash™ Service offers the option of programming and protecting sectors at
the factory prior to shipping the device. Contact a sales office or representative
for details.
It is possible to determine whether a sector is protected or unprotected. See
