upisemi,continuous:
$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.
