3.12 Multimedia Card/Secure Digital Host Controller
The DMA interface block controls all data routing between the external data bus (DMA access), internal
MMC/SD module data bus, and internal system FIFO access through a dedicated state machine that
monitors the status of FIFO content (empty or full), FIFO address, and byte/block counters for the
MMC/SD module (inner system) and the application (user programming).
