Class 0 is mandatory and supported by all cards. It represents the card identification and initialization
commands, which are intended to handle different cards and card types on the same bus lines. The Card
Command Class (CCC) is coded in the card specific data register of each card, so that the host knows how
to access the card. There are four kinds of commands defined on the MultiMediaCard bus:
broadcast commands (bc) sent on CMD line, no response
broadcast commands with response (bcr) sent on CMD line, response (all cards simultaneously) on
CMD line
addressed (point-to-point) commands (ac) sent on CMD line, response on CMD line
addressed (point-to-point) data transfer commands (adtc) sent on CMD line, response on CMD line,
data transfer on DAT line
