MMC_CS0, which corresponds to the applications processor MMCCS0 signal, is connected to the socket at pin 1. This connection is the SPI mode chip select and is available on both MMC and SDCard. This pin is also labeled DAT3. DAT3 is only used with an SDCard in SDCard mode and not available on the applications processor MMC controller.

The signals DAT1 and DAT2 are not connected because these are specific to SDCard operation in SDCard mode.
