| $ref: /schemas/types.yaml#/definitions/flag |
| description: | |
| This chip has two power modes: one-shot (chip takes one measurement and |
| then shuts itself down) and continuous (chip takes continuous |
| measurements). The one-shot mode is more power-friendly but the |
| continuous mode may be more reliable. If this property is specified |
| the continuous mode will be used instead of the default one-shot one for |
| raw reads. |
