User-Defined DIP Switches
Board reference S7 is a 4-pin DIP switch. The switches are user-defined and provided
for additional FPGA input control. There is no board-specific function for these
switches.
Table 2–25 lists the user-defined DIP switch schematic signal names and their
corresponding Cyclone III LS pin numbers.
Table 2–26 lists the user-defined DIP switch component reference and the
manufacturing information.
