Sector/Sector Block Protection and Unprotection
The hardware sector protection feature disables both programming and erase operations in any
sector. The hardware sector unprotection feature re-enables both program and erase operations
in previously protected sectors. Sector protection/unprotection can be implemented via two
methods.
(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
Tab le , “,” on page 18 and Tabl e , “,” on page 21).)
