There are a total of 15 active-High LEDs directly controllable by the FPGA:
•
Eight green LEDs are general purpose LEDs arranged in a row
•
Five green LEDs are positioned next to the North-East-South-West-Center-oriented
pushbuttons (only the center one is cited in
•
Two red LEDs are intended to be used for signaling error conditions, such as bus
errors, but can be used for any other purpose
Some LEDs are buffered through the CPLD to allow the LED signals to be used as higher-
performance I/O by way of the XGI expansion connector.
