Part 7.7: User Buttons

On the AX7020 development board, four user buttons are connected to the
IOs of BANK34 and Bank35 in the ZYNQ PL section. The buttons are active
low. In the circuit design, when the button is pressed, the signal is low, and
when it is not pressed, the signal is high. The schematic is shown in Figure
7-15:
