SD/MMC Card Interfaces
The phyCORE-i.MX7 provides three SD/MMC interfaces: SD/MMC1-3. SD/MMC1 and SD/MMC2 are provided at the
phyCORE connector directly from the processor. These two ports allow support for external SD/MMC devices, such as an
SD card or a WiFi/Blueooth module, and are provided with 22 Ohm source termination resistors on the SOM. The
SD/MMC3 interface is used to interface with an on-board flash device, either eMMC at U5 or NAND at U6 depending on
the SOM configuration (see Section 7.2).
