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.

Annotation
- Atlas domain: Support Tooling And Documentation / Documentation.
- Implementation status: atlas-only.
Implementation Notes
- This generated page is the file-by-file coverage layer; curated subsystem chapters should link here when they synthesize a multi-file control flow.
- Core OS pages should be promoted from atlas-only to deep-reviewed when they explain data structures, invariants, locking, lifecycle, and C implementation snippets.
- Driver-family pages are intentionally pattern-oriented unless they are part of the selected PCIe/NVMe representative device path.
