12. FPGA INIT and DONE LEDs

The typical Xilinx FPGA power up and configuration status LEDs are present on the SP601. The INIT LED DS10 comes on after the FPGA powers up and completes its internal power-on process. The DONE LED DS9 comes on after the FPGA programming bitstream has been downloaded and the FPGA successfully configured.
