SAM E54 Xplained Pro

5.3.2 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.
