  slow-io-gpios:
    description:
      A GPIO used to trigger a change is sampling rate (lowering the chip power
      consumption). If configured in SLOW mode, if this pin is forced high,
      sampling rate is forced to eight samples/second. When it is forced low,
      the sampling rate is 1024 samples/second unless a different sample rate
      has been programmed.

          Value in micro Ohms of the shunt resistor connected between
          the SENSE+ and SENSE- inputs, across which the current is measured.
          Value is needed to compute the scaling of the measured current.
