User-Defined DIP Switch (S5)

Board reference S5 is an eight-pin DIP switch. The DIP switches in S5 are

user-defined, and are provided for additional FPGA input control. Each

pin can be set to a logic 1 by pushing it to the open position, and each pin

can be set to logic 0 by pushing it to the closed position.

Table 2–14 lists the DIP switch settings, schematic signal name, and

corresponding Stratix II GX device’s pin number.

Figure 2–9 shows the user-defined DIP switch board image.
