MultiMedia Card Operations
Figure 30-8. Mixing MultiMedia and SD Memory Cards with Two Slots
When the MCI is configured to operate with SD memory cards, the width of the data bus can be
selected in the SDCard /SDIO Bus Width field in the SDCR register (SDCR.SDCBUS).
tion “30.7.4” on page 850.
In the case of multimedia cards, only the data line 0 is used. The other data lines can be used as
independent GPIOs.
After a power-on reset, the cards are initialized by a special message-based MultiMedia Card
bus protocol. Each message is represented by one of the following tokens:
Card addressing is implemented using a session address assigned during the initialization
phase by the bus controller to all currently connected cards. Their unique CID number identifies
individual cards.
The structure of commands, responses and data blocks is described in the MultiMedia-Card
System Specification. Refer also to
MultiMediaCard bus data transfers are composed of these tokens.
• Command: a command is a token that starts an operation. A command is sent from the host
• Response: a response is a token which is sent from an addressed card or (synchronously)
• Data: data can be transferred from the card to the host or vice versa. Data is transferred via
either to a single card (addressed command) or to all connected cards (broadcast
command). a command is transferred serially on the CMD line.
from all connected cards to the host as an answer to a previously received command. A
response is transferred serially on the CMD line.
