22. Program Switch

The active-low program switch, when pressed, grounds the program pin on the DUT. This 
switch is driven indirectly by the Service FPGA.

23. Reset Switch (Active-Low)

The reset switch connects (indirectly through the Service FPGA) to the INIT pin on the 
DUT, allowing the user, after configuration, to reset the logic within the DUT. Before and 
during configuration of the DUT, the INIT pin has no function. After configuration, the 
INIT

 pin becomes a regular I/O. When pressed, this switch grounds the INIT pin.

24. DONE LED

The DONE LED indicates the status of the DONE pin on the DUT. This LED lights when 
DONE

 is high or if power is applied to the board without a part in the socket.

25. INIT LED

The INIT LED lights during initialization.
