Interfaces

User Push-Buttons

The four user push-buttons are intended for use in controlling FPGA

designs loaded into the Cyclone III device. There is no board-specific

function for these four push-buttons.

LEDs

The board has user LEDs and board-specific LEDs. Table 2–10 lists both

user and board-specific LED pinout. A logic “0” illuminate the LEDs.

Figure 2–6 shows the LEDs.

User LEDs

Status and debugging signals are driven to the user LEDs from FPGA

designs loaded into the Cyclone III device. There is no board-specific

function for the user LEDs.
