50      This chip has two power modes: one-shot (chip takes one measurement and
51      then shuts itself down) and continuous (chip takes continuous
52      measurements). The one-shot mode is more power-friendly but the
53      continuous mode may be more reliable. If this property is specified
54      the continuous mode will be used instead of the default one-shot one for
55      raw reads.
