This device contains one instance of the Multimedia Card (MMC), Secure Digital (SD), and Secure Digital I/O (SDIO) high speed interface module (MMCSD). The controller provides an interface to an MMC, SD memory card or SDIO card.
The application interface is responsible for managing transaction semantics; the MMC/SDIO host controller deals with MMC/SDIO protocol at transmission level, packing data, adding CRC, start/end bit and checking for syntactical correctness. Figure 13-169 through Figure 13-171 below show examples of systems using the MMCSD controller.
