Configuration And Related Signals - Intel Agilex Configuration User Manual

SD/MMC
SD/MMC is an active configuration scheme. The Intel Agilex SDM can initiate configuration from SD, Secure Digital High
Capacity (SDHC*). Secure Digital Extended Capacity (SDXC*), MMC cards, and eMMC devices. The SD/MMC mode is almost
identical to AS x4. The advantages of this mode are cost, capacity, availability, portability, and compatibility. Because Intel
Agilex devices operate at 1.8 volt an intermediate voltage level shifter may be required to interface with the higher voltage
I/Os in SD/MMC devices.
Note: The SD/MMC configuration scheme is not supported in the current release.
