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 5
and
Table 6
).

Top Boot Sector/Sector Block Addresses
for Protection/Unprotection
Table 6.

Bottom 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. Sector protection/unprotection is implemented
via two methods.
