The adxl345 sensor uses one of two interrupt lines, INT1 or INT2. The
interrupt lines are used to signal feature events such as watermark
reached, single tap, double tap, activity, etc. Only one interrupt line
is used and must be configured. The adxl345 default is to use INT1 and
in many installations only INT1 is even connected. Therefore configure
INT1 as the sensor's default interrupt line.
