Part 3.13: LED Light
There are seven red LEDs on the AX7103 FPGA carrier board, one of
which is the power indicator (PWR), two are USB Uart data receiving and
transmitting indicators, and four are users LED lights (LED1~LED4). When the
board is powered on, the power indicator will light up; User LED1~LED4 are
connected to the normal IO of the FPGA. When the IO voltage connected to the
user LED is configured low level, the user LED lights up. When the connected
IO voltage is configured as high level, the user LED will be extinguished. The
