Secure Digital Host Controller (SDHC)
28.2
28.2.1
28.2.1.1
The SDHC has six external pins. MMC_SD_CLK is an internally generated clock used by the MMC/SD
Card. The CMD I/O sends commands and receive responses from the card. Four data lines, DAT3~DAT0,
perform data transfers between the host controller and the
these external pins.
