DIP Switch, LEDs and Push Buttons
DIP Switch S1
Eight signals are provided for debug purposes. The signals toggle between 0 V (low) and 3.3 V (high) logic. The signals
are controlled by the A3P250 FPGA.
LEDs
Four green LEDs (D6, D7, D8 and D9) and four red LEDs (D10, D11, D12 and D13) are provided for debug
purposes. The LEDs are controlled by the A3P250 FPGA. If the signals are at logic high, the LEDs are On. If the
signals are driven low, the LEDs are Off.
