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.
Power Management
Interrupt
The MCI may be clocked through the Power Management Controller (PMC), so the programmer
must first configure the PMC to enable the MCI clock.
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.
Figure 37-3. Multimedia Memory Card Bus Topology
The MultiMedia Card communication is based on a 7-pin serial bus interface. It has three com-
munication lines and four supply lines.
