The MMCSD Host Controller provides an interface to embedded Multi-Media Card (MMC), Secure Digital (SD), and Secure Digital IO (SDIO) devices. The MMC/SD controller deals with MMC/SD/SDIO protocol at transmission level — packing data, adding CRC, start/end bit, and checking for syntactical correctness.
The MMCSD Host Controller has been implemented as a 4-bit subsystem and 8-bit subsystem. The 4-bit subsystem supports removable SD cards compliant with the SD Physical Layer Specification v3.01, and embedded SDIO devices compliant with the SDIO Specification v3.00. The 8-bit subsystem supports eMMC devices compliant with the JEDEC eMMC electrical standard v5.1 (JESD84-B51), and embedded SDIO devices compliant with the SDIO Specification v3.00.
