The board supports Micro SD card interface with x4 data lines. It serves not only an external
storage for the HPS, but also an alternative boot option for DE1-SoC board. Figure 3-33 shows
signals connected between the HPS and Micro SD card socket.
Table 3-28 lists the pin assignment of Micro SD card socket to the HPS.
