Board Components & Interfaces

User LEDs (D9 Through D16)

The board provides eight user-defined LEDs. A logic 0 driven to an LED

turns it off; a logic 1 driven to an LED turns it on.

Table 2–15 lists the schematic signal name and the corresponding

Stratix II GX device’s pin number.

Configuration DIP Switch (S6)

The configuration DIP switch is used to set up specific board functions,

such as FPGA bootstrap settings, JTAG chain bypassing, or configuration

setup. In the open position, the selected signal is driven to logic 0. In the

closed position, the selected signal is driven to a logic 1.
