7. LEDs and Switches

This section describes the CrossLink-NX Evaluation Board LEDs and switches that can be used in demo and customer
designs.

7.1. DIP Switch

Eight CrossLink-NX pins are connected to the SW1 DIP switch to allow for manually actuated inputs to the FPGA. One
side of each switch is connected to GPIOs within the VCCIO2 bank and pulled up through 4.7 kΩ resistors. The other
side is grounded. The designated pins are connected as shown in

Table 7.1. Eight-Position DIP Switch Signals

7.2. General Purpose Push Buttons

The CrossLink-NX Evaluation Board provides three push button switches – SW2, SW3 and SW4 for demos and user
applications. Two of the buttons control pre-defined functional pins, and the third is generic. Pressing these buttons
drives a logic level "0" to the corresponding I/O pins.
