6.10 Multimedia Card/Secure Digital (MMC/SD)
The VC5504 includes two MMC/SD controllers which are compliant with MMC V3.31, Secure Digital Part 1
Physical Layer Specification V2.0, and Secure Digital Input Output (SDIO) V3.3 specifications. The
MMC/SD card controller supports these industry standards and assumes the reader is familiar with these
standards.
Each VC5504 MMC/SD Controller has the following features:
• Multimedia Card/Secure Digital (MMC/SD) protocol support
• Programmable clock frequency
• 512 bit Read/Write FIFO to lower system overhead
• Slave DMA transfer capability
The MMC/SD card controller transfers data between the CPU and DMA controller on one side and
MMC/SD card on the other side. The CPU and DMA controller can read/write the data in the card by
accessing the registers in the MMC/SD controller.
The MMC/SD controller on this device, does not support the SPI mode of operation.
For more detailed information, see the TMS320VC5505 DSP Multimedia Card (MMC)/Secure Digital (SD)
Card Controller User's Guide (literature number SPRUFO6).
