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.
