title: Tegra210 DMIC Controller
description: |
The Digital MIC (DMIC) Controller is used to interface with Pulse
Density Modulation (PDM) input devices. It converts PDM signals to
Pulse Coded Modulation (PCM) signals. DMIC can be viewed as a PDM
receiver.

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.
