Part 3.20: Keys
There are 1 reset KEY RESET and 2 user KEYs on the AXU7EV carrier
board. The reset signal is connected to the reset chip input of the core board
ACU7EV, and the user can use this reset KEY to reset the ZYNQ system. One
user KEY is connected to the MIO of the PS, and one is connected to the IO of
the PL. The reset KEY and the user KEYs are both low-level active. The
