Secure digital input/output and MultiMediaCards interface

(SDMMC)

The SDMMC (SD/SDIO embedded MultiMediaCard e•MMC™ host interface) provides

an interface between the AHB bus and SD memory cards, SDIO cards and e•MMC devices.

The MultiMediaCard system specifications are available through the MultiMediaCard

association website at www.mmca.org, published by the MMCA technical committee.

SD memory card and SD I/O card system specifications are available through the SD card

Association website at www.sdcard.org.
