Sector Protection Verification
Description
The autoselect codes may also be accessed in-system via command sequences. See Table 9.
Autoselect Mode
Sector Protection/Unprotection
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 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
4
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 Table 9. This method does
not require V
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 shipped with all sectors unprotected. Spansion offers the option of
programming and protecting sectors at its factory prior to shipping the device
through Spansion’s ExpressFlash™ Service. Contact a Spansion representative
for details.
