SD SDIO eMMC MSPro MSPro-Duo CF+ xD Multi-function Host Controller IP
The SD3.0/SDIO3.0/MMC4.5/Memory Stick/Memory Stick Pro/CF+/xD Host Controller is a Multi-Function Host Controller with a ARM processor interface. This Host Controller handles SD/SDIO/MMC/MEM Stick/Mem Stick PRO/ CF+/xD memory protocols at transmission level, packing data, adding cyclic redundancy check (CRC), start/end bit, and checking for transaction format correctness.
The IP core provides Programmed IO method and DMA data transfer method. In programmed IO method, the ARM processor transfer data using the Buffer Data Port Register. Host controller support for DMA can be determined by checking the DMA support in the Capabilities register. DMA allows a peripheral to read or write memory without the intervention from the CPU. The system address register points to the first data address, and data is then accessed sequentially from that address. The controller supports both types of CF devices: CF Storage cards, and CF+ cards. It implements the CF+ host side interface utilizing PC Card ATA using I/O mode, PC Card ATA using memory mode, and True IDE mode.The controller also implements the xD Card interface protocol to connect the xD Picture cards.
