Autoselect Mode
The autoselect mode provides manufacturer and de-
vice identification, and sector protection verification,
through identifier codes output on DQ7
–
DQ0. This
mode is primarily intended for programming equip-
ment to automatically match a device to be
programmed with its corresponding programming al-
gorithm. However, the autoselect codes can also be
accessed in-system through the command register.
To access the autoselect codes in-system, the host
system can issue the autoselect command via the
command register, as shown in Tables 16 and 18. This
method does not require V
ID
. Refer to the Autoselect
Command Sequence section for more information.
Sector/Sector Block Protection and
Unprotection
(Note: For the following discussion, the term
“
sector
”
applies to both sectors and sector blocks. A sector
block consists of two or more adjacent sectors that are
protected or unprotected at the same time (see Table
10).
Table 10.
Addresses for Protection/Unprotection
Top Boot Sector/Sector Block
The hardware sector protection feature disables both
program and erase operations in any sector. The hard-
ware sector unprotection feature re-enables both
program and erase operations in previously protected
sectors. Note that the sector unprotect algorithm un-
protects all sectors in parallel. All previously protected
sectors must be individually re-protected. To change
data in protected sectors efficiently, the temporary
sector un protect function is available. See
“
Temporary
Sector/Sector Block Unprotect
”
.
