Short circuiting an output pin to a power supply pin (Power-supply voltage VDD and LED anode power supply),
or short-circuiting the REXT pin to the GND pin will likely exceed the absolute maximum ratings, which in turn
may result in smoldering and/or permanent damage. Please keep this in mind when determining the wiring
layout for the power supply and GND pins.
