40    description: Default value is 0 which configures the normal polarity of the
41      ALERT pin, being active low open-drain. Setting this to 1 configures the
42      polarity of the ALERT pin to be inverted and active high open-drain.
43      Specify this property to set the alert polarity to active-high.
