SDIO functional description

The SDIO consists of two parts:
• The SDIO 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 SDIO adapter registers, and generates interrupt and
DMA request signals.
