Configuration Status Indicators
(see Appendix A, Figure 23)
These LEDs indicate the status of configuration to the FPGA.
• D8 (red) illuminated, this indicates that the programming was aborted or reinitialized driving the INITN output low.
• D11 (green) illuminated, this indicates the successful completion of configuration by releasing the open collector
DONE output pin.
• D12 (green) will flash indicating TDI activity.
