The board supports Micro SD card interface with x4 data lines. Through the load switches
(U25/U26) and voltage-translation transceiver (U22), user can select 1.8V or 3.3V VCCIO power of
Micro SD card to implement external storage application.
Figure 3-30
shows signals connected
between the MAX 10 FPGA and Micro SD card socket.
Table 3-21
lists the pin assignment of Micro SD card socket to the MAX 10 FPGA.
