    I see this has been answered before.

    However, how should DEN_A/G be connected? Gnd, Vdd, floating?

    Hi Damon, you can connect DEN_A/G pin to your MCU without initializing it, if you don't need to use it.

    If I'm not using it, should I connect it to GND or Vdd?

    Hi Damon, yes, connecting to GND should be ok

    Hi from my understanding that DEN is a I/O pin that creates a trigger to Automatically send data to the MCU. This can be used instead of a standard i2c or spi call?

    This pin seems very dangerous as there is very very little info on how to use it correctly.

    So grounding this pin is for the best until the documentation is updated.
