2.7 SDHC interface

The FRWY-LS1046A supports connections with the enhanced secure digital host controller (eSDHC) of the LS1046A processor

through a micro-SDHC connector that accepts an external micro-SD 3.0 card. The micro-SD card is one of the primary boot

sources of the board. The figure below shows the SDHC diagram of the FRWY-LS1046A.
