| 49 | description: | |
| 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. |
