Signal Description; Emmc Flash; Emmc Flash Type; Sd Card Signals - Enclustra Mercury SA1 SoC Module User Manual

Starting with revision 3 modules, access to the SD card is conditioned by the state of EMMC_EN# signal
(eMMC flash enable).
Please note that external pull-ups are needed for SD card operation. Depending on the selected voltage
for VCC_CFG_HPS_B3A_B8A, a level shifter to 3.3 V may be required (some level shifters also have built-in
pull-ups).
