Revision 0.3
6. MultiMediaCard Protocol Description
All communication between host and card is controlled by the host (master). The host sends commands of two types:
broadcast and addressed (point-to-point) commands.
Broadcast commands : Broadcast commands are intended for all cards in a MultiMediaCard system
1
. Some of these
commands require a response.
Addressed (point-to-point) commands : The addressed commands are sent to the addressed card and cause a
response from this card.
A general overview of the command flow is shown in Figure 6-1 for the card identification mode and in Figure 6-2 for the
data transfer mode. The commands are listed in the command tables (Table 6-9 - Table 6-17). The dependencies between
current state, received command and following state are listed in Table 6-18. In the following sections, the different card
operation modes are described first. Thereafter, the restrictions for controlling the clock signal are defined. All MultiMedi-
aCard commands together with the corresponding responses, state transitions, error conditions and timings are presented
in the succeeding sections.
Three operation modes are defined for the MultiMediaCard system (hosts and cards):
Card identification mode
The host will be in card identification mode after reset, while it is looking for a card on the bus. The card will be in this
mode after reset, until the SET_RCA command (CMD3) is received.
Interrupt mode
Host and card enter and exit interrupt mode simultaneously. In interrupt mode there is no data transfer. The only mes
sage allowed is an interrupt service request from the card or the host.
Data transfer mode
The card will enter data transfer mode once an RCA is assigned to it. The host will enter data transfer mode after iden
tifying the card on the bus.
The following table shows the dependencies between bus modes, operation modes and card states. Each state in the
MultiMediaCard state diagram (see Figure 6-1 and Figure 6-2) is associated with one bus mode and one operation mode:
1.Broadcast commands are kept for backwards compatibility to previous MultiMediaCard systems, where more than one
card was allowed on the bus.
