41.3 SDMMC functional description
The SDMMC consists of two parts:
• The SDMMC adapter block provides all functions specific to the MMC/SD/SD I/O card
such as the clock generation unit, command and data transfer.
• The APB2 interface accesses the SDMMC adapter registers, and generates interrupt
and DMA request signals.
