Figure 35-7. SD Card Bus Connections with Two Slots
Note:
Figure 35-8. Mixing MultiMedia and SD Memory Cards with Two Slots
Note:
When the MCI is configured to operate with SD memory cards, the width of the data bus can be
selected in the MCI_SDCR register. Clearing the SDCBUS bit in this register means that the
width is one bit; setting it means that the width is four bits. In the case of multimedia cards, only
the data line 0 is used. The other data lines can be used as independent PIOs.
When several MCI (x MCI) are embedded in a product, MCCK refers to MCIx_CK,MCCDA to
MCIx_CDA, MCDAy to MCIx_DAy, MCCDB to MCIx_CDB, MCDBy to MCIx_DBy.
