Each WP-group may have an additional write protection bit. The write protection bits are programmable
via special commands (refer to Chapter “Commands”). Both functions are optional and only useful for
writable/erasable devices. The write protection may also be useful for multi type MultiMediaCards (e.g. a
ROM - Flash combination). The information about the availability is stored in the CSD.
