— Sector Protection features:
— Provides a software method of detecting program
or erase cycle completion
Hardware method of locking a sector to prevent
any program or erase operations within that sector
■ Erase Suspend/Resume
Sectors can be locked via programming
equipment
— Supports reading data from or programming data
to a sector not being erased
