40.7 Functional Description

SD/SDIO Operating Mode

This peripheral is fully compliant with the "SD Host Controller Simplified Specification V3.00" for SD/SDIO devices. Refer to this specification for configuration.

e.MMC Operating Mode

This peripheral supports e.MMC devices management. As the "SD Host Controller Simplified Specification V3.00" does not apply to e.MMC devices, some registers have been added to those described in this specification in order to manage e.MMC devices. Most of the registers described in the "SD Host Controller Simplified Specification V3.00" must be used for e.MMC management, but e.MMC- specific features are managed using SDHC_MC1R and SDHC_MC2R.
