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.
