SWPU176A–October 2009 MMC/SD/SDIO Card Interface 3445
3.12.2.10 MMC/SD/SDIO
The Multimedia card high speed/ SD /SDIO(MMC/SD/SDIO) host controller provides an interface between a local host
such as a microprocessor unit or digital signal processor and either MMC, SD memory cards or SDIO cards and handles
MMC/SD/SDIO transactions with minimal local host intervention.
