Enhanced Sector Protect/Un-protect
This device is set from the factory in the Individual Protection mode of the Enhanced Sector Protect
scheme. The user can disable or enable the programming or erasing operation to any individual sector
or whole chip. The figure below helps describe an overview of these methods.
The device defaults to the Individual mode and all sectors are unprotected when shipped from the
factory.
The following flow chart shows the detailed algorithm of Enhanced Sector Protect:
