3.3. SD/MMC Configuration
Note: Contact your Intel sales representative for information about SD/MMC support.
In the configuration scheme using SD memory cards or MMC, the memory cards store configuration data. The SDM uses the
on-chip SD or MMC controller to interface to the memory cards. The SDM block reads the configuration data from the memory
cards for the configuration process. The configuration from SD and MMC supports x4 SD memory cards and x8 MMC.

Note:
Although the CONF_DONE and INIT_DONE configuration signals are not required, Intel recommends that you use these
signals. The SDM drives the CONF_DONE signal high after successfully receiving full bitstream. The SDM drives the
INIT_DONE signal high to indicate the device is fully in user mode. You can reassign the GPIO, dual-purpose configuration
pins for other functions in user mode.
