40.6.2 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 MC1R and MC2R.
