Table 2–23 lists the user-defined push-button switch schematic signal names and their

corresponding Cyclone III LS device pin numbers.

Table 2–24 lists the user-defined push-button switch component reference and the

manufacturing information.

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.
