Host Protected Area Feature Set
A reserved area for data storage outside the normal operating system file system is required for several specialized
applications. Systems may wish to store configuration data or save memory to the device in a location that the operating
systems cannot change. The optional Host Protected Area feature set allows a portion of the device to be reserved for
such an area when the device is initially configured.
