Bus Topology
When several MCI (x MCI) are embedded in a product, MCCK refers to MCIx_CK, MCCDA to MCIx_CDA MCDAy to MCIx_DAy.
AT91SAM9R64/RL64
Interrupt
The MCI interface has an interrupt line connected to the Advanced Interrupt Controller (AIC).
Handling the MCI interrupt requires programming the AIC before configuring the MCI.
The MultiMedia Card communication is based on a 7-pin serial bus interface. It has three com-
munication lines and four supply lines.
