Short Cut Protection
The MultiMediaCards can be inserted/removed into/from the bus without damage. If the card
insertion/removal is occured during card operation (read/write), the data in the MultiMediaCard would be
broken. If one of the supply pins (V
CC
or V
SS
) is not connected properly, then the current is drawn through
a data line to supply the card. Naturally the card can not operate properly under this conditions.
