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 MAX 10 NEEK board.
Figure 3-34
shows signals connected between the HPS and Micro SD card socket.
Table 3-20
lists the pin assignment of Micro SD card socket to the MAX 10 FPGA.
