Prog Push Button; Done Led; Init Led - Xilinx SP623 User Manual

The JTAG chain of the board is illustrated in
isolation jumpers described in
on header J162 automatically bypasses the FMC modules and the GTP transceiver power
supply module in the chain.

PROG Push Button

[Figure
Pressing the PROG push button (SW5) grounds the active-Low program pin of the FPGA.

DONE LED

[Figure
The DONE LED (DS6) indicates the status of the DONE pin of the FPGA. When the DONE
pin is high, DS6 lights indicating the FPGA is successfully configured.

INIT LED

[Figure
The INIT LED (DS20) lights during FPGA initialization.
