There are 16 active-high user LEDs on the board. Before configuration, the LEDs reflect the
status of the configuration mode pins. During configuration, the LEDs are in a high-
impedance condition. After configuration, the LEDs are available to the user and reflect the
status of pins D0-D7 and D24-D31 (corresponding to LED 0- LED 15). The LED
assignments are shown in
