FPGA Pin Function Notes
3 D2 LED Low to Light LED
7 D4 LED Low to Light LED
9 D5 LED Low to Light LED
144 Pushbutton Push to ground, no external pullup. Set internal pullup on FPGA configuration if used.
17 50MHz clock input
73 10uF capacitor to ground 10K resistor to Vcc, for power up reset if needed?
26 Connected to Vcc 1.2V Only needed for EPC28. The "zero ohm" resistor could be removed and the pin used as normal.
27 Connected to GND Only needed for EPC28. The "zero ohm" resistor could be removed and the pin used as normal.
80 Connected to GND Only needed for EPC28. The "zero ohm" resistor could be removed and the pin used as normal.
81 Connected to Vcc 1.2V Only needed for EPC28. The "zero ohm" resistor could be removed and the pin used as normal.
