Per the XPlained board's Hardware Guide

6.1 Mechanical button switches
Eight mechanical button switches are connected to XMEGA PORTD(PD0:PD5) and
PORTR(PR0:PR1). Internal pull-ups should be enabled to detect when the buttons
are pushed, as they short the respective line to GND.

NOTE: Buttons share the pins with the J3 header: Pushing the buttons potentially affects
communication or other functionality on these pins.
