A highly sophisticated protection method that requires a password before
changes to certain sectors or sector groups are permitted
WP# Hardware Protection
A write protect pin that can prevent program or erase operations in the outermost
sectors.
The WP# Hardware Protection feature is always available, independent of the
software managed protection method chosen.

Sector Protection Mode Locking Bit
. This will permanently set the part to op-
