Be careful not to hot swap when JTAG cable is plugged and unplugged.
Part 4.11: Buttons
The FPGA carrier board contains two user buttons KEY1~KEY2. All
buttons are connected to the normal IO of the FPGA. The button is active low.
When the button is pressed, the IO input voltage of the FPGA is low. When no
button is pressed, The IO input voltage of the FPGA is high. The circuit of the
button part is shown in Figure 4-11-1.
