title: Cirrus EP93xx I2S Controller
description: |
The I2S controller is used to stream serial audio data between the external
I2S CODECs’, ADCs/DACs, and the ARM Core. The controller supports I2S, Left-
and Right-Justified DSP formats.

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.
