I/O Lines Description
The pins used for interfacing the MultiMedia Cards or SD Cards may be multiplexed with PIO
lines. The programmer must first program the PIO controllers to assign the peripheral functions
to MCI pins.
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 35-3. 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.
