Media Card detect. This input is asserted when an UltraMedia adapter and its associated
media are inserted. For all other UltraMedia cards, the UltraMedia socket is not powered
until this signal is low.
UltraMedia write protect data. This signal indicates that the media inserted in the socket is
write protected.
