Overview
Four green LEDs are incorporated into the development board and are
used to display the required status. In addition, two LEDs are reserved to
signify power supply and FPGA loading status.
Users can test the LEDs in the following ways:
If the output signal of related pins is logic low, LED is on;
If the logic is high, LED is off.
