FPGA INIT and DONE LEDs
The typical Xilinx FPGA power up and configuration status LEDs are present on the
SP605.
The red INIT LED DS17 comes on momentarily after the FPGA powers up and during its
internal power-on process. The DONE LED DS2 comes on after the FPGA programming
bitstream has been downloaded and the FPGA successfully configured.
