• Manufacturer Part Number: MC9328MX1/D
• Description: i.MX Integrated Portable System Processor
• Manufacturer: ETC

Specifications
3.15 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).
