User LEDs
Status and debugging signals are driven to the user LEDs from FPGA
designs loaded into the Cyclone III device. There is no board-specific
function for the user LEDs.
Board Specific LEDs
The power LED illuminates when the board’s power is on and working.
The configuration done LED illuminates when the FPGA is programmed.
■
Configuration LED: The
Conf_Done
LED illuminates when the
FPGA is successfully configured with any design
■
Flash signal LED: The
flash_CE_n
LED illuminates when the
CE_n
signal to the flash is asserted indicating the flash is being accessed.
■
Power LED: The power LED illuminates when power is applied to
the board.
