Part 18: LED

There are six red LEDs on the AX515 FPGA development board, one of
which is the power indicator (PWR), four are users LED lights (LED1~LED4).
The schematic of the four user LED sections is shown in Figure 18-1. When the
FPGA pin output is logic 0, the LED will go out. When the output is logic 1, the
LED is illuminated.
