3.3.2 Push Buttons
The board has two push buttons connected to the FPGA. MAX10 devices support Schmitt trigger
input on all I/O pins. A Schmitt trigger feature introduces hysteresis to the input signal for
improved noise immunity, especially for signal with slow edge rate and acts as switch debouncer.
Push buttons drive their associated pins low logic level when pressed and high logic level when
released.
