SDIO controller/MMC card interface

The SDIO host controller has an AMBA compatible interface and conforms to the SD host

controller standard specification version 2.0. It handles SD/SDIO protocol at transmission

level, packing data, adding cyclic redundancy check (CRC), start/end bit, and checking for

transaction format correctness.

Main features:

●

Meets the following standard specifications:

–

SD host controller standard specification version 2.0

–

SDIO card specification version 2.0

–

SD memory card specification draft version 2.0

–

SD memory card security specification version 1.01

–

MMC specification version 3.31 and 4.2

●

Supports both DMA and non-DMA mode of operation

●

Supports MMC plus and MMC mobile

●

Card detection (insertion/removal)

●

Password protection of cards

●

Host clock rate variable between 0 and 48 MHz

●

Supports 1-bit, 4-bit and 8-bit SD modes and SPI mode

●

Supports Multi Media Card interrupt mode

●

Allows card to interrupt host in 1-bit, 4-bit, 8-bit SD modes and SPI mode.

●

Up to 100 Mbit/s data rate using 4 parallel data lines (sd4-bit mode)

●

Up to 416 Mbit/s data rate using 8-bit parallel data lines (sd8-bit mode)

●

Cyclic redundancy check CRC7 for command and CRC16 for data integrity

●

Designed to work with I/O cards, read-only cards and read/write cards

●

Error correction code (ECC) support for MMC4.2 cards

●

Supports read wait control, suspend/resume operation

●

Supports FIFO overrun and underrun condition by stopping the SD clock

●

Conforms to AMBA specification AHB (2.0)
