Assignment of a display to Display Select pins
Automatic configuration of one of 15 possible displays is performed by means of
the Display Select inputs. The Display Select inputs have pull-up resistors – in
other words, if these inputs are not connected, they go to High. The input has to be
connected to GND for them to go Low.
