MultiMediaCardTM
4.9.9 Reset
GO_IDLE_STATE (CMD0) is the software reset command, which sets the MultiMediaCard into the Idle
State independently of the current state. In the Inactive State the MultiMediaCard is not affected by this
command. After power-on the MultiMediaCard is always in the Idle State. After power-on or command
GO_IDLE_STATE (CMD0) all output bus drivers of the MultiMediaCard is in a high-impedance state and
the card will be initialized with a default relative card address (“0x0001”). The host runs the bus at the
identification clock rate fOD generated by a push-pull driver stage (refer to also Chapter “Power on” for
more details).
