The PrimeCell MultiMedia Card Interface (MMCI) is instantiated into the core module FPGA. A card connector is provided by the baseboard and the interface signals are routed between the core module and baseboard using the HDRB connectors.

The MMCI is an APB peripheral that provides an interface between the MMC and the APB. For detailed information, see the PrimeCell MultiMedia Card Interface (PL181) Technical Reference Manual.
