JUMPER connection
One hand-soldered jumper (JP31) on the EVB is used to set the GPIO0 pin input. In position 1-2 (default), the NTC (NTC1) is connected
to GPIO0 pin of the MC33771. This input can be used as analog input. If the jumper is placed in position 2-3, the GPIO0 can be used as
fault input for fault daisy chain function.
