The MMCSD Host Controller provides an interface to embedded Multi-Media Card (MMC), Secure Digital (SD), and Secure Digital IO (SDIO) devices. The MMCSD Host Controller deals with MMC/SD/SDIO protocol at transmission level, data packing, adding cyclic redundancy checks (CRCs), start/end bit insertion, and checking for syntactical correctness.
For more details about MMCSD interfaces, see the corresponding MMC0, MMC1, and MMC2 subsections within Signal Descriptions and Detailed Description sections.
Some operating modes require software configuration of the MMC DLL delay settings, as shown in Table 6-81 and Table 6-99.
The modes which show a value of "Tuning" in the ITAPDLYSEL column of Table 6-81 and Table 6-99 require a tuning algorithm to be used for optimizing input timing. Refer to the MMCSD Programming Guide in the device TRM for more information on the tuning algorithm and configuration of input delays required to optimize input timing.
For more information, see Multi-Media Card/Secure Digital (MMCSD) Interface section in Peripherals chapter in the device TRM.
