+  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.

+    description:
+      In default mode, this pin is a GPIO input pin. It can be
+      configured to be an output pin, as well as the ALERT2
+      function. This pin is an open-drain configuration and
+      needs a pull-up resistor to VDD.
