5.3.5.2 BPL010-503 - Active low inputs
The user power supply connection USR V+ is common to all inputs. To activate an input it
must be grounded to the 0 V side of the user power supply (USR GND). The internal pull-up
resistor on the NextMove ES allows the input to be left floating when inactive or not being
used.
