PRODUCTION DATA
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 sections within
Signal Descriptions and Detailed Description.
Some operating modes require software configuration of the MMC DLL delay settings, as shown in Table 7-57 and Table 7-67.
For more information, see Multi-Media Card/Secure Digital (MMCSD) Interface section in Peripherals chapter in the device TRM.
