Mechanical Buttons

SAM E54 Xplained Pro contains two mechanical buttons. One button is the RESET button connected to the SAM E54 reset line and the other is a generic user configurable button. When a button is pressed it will drive the I/O line to GND.

Info: There is no pull-up resistor connected to the generic user button. Remember to enable the internal pull-up in the SAM E54 to use the button.
