description:
The RTC provides up to three clocks
- the Low Frequency Oscillator or LOSC, at index 0,
- the Low Frequency Oscillator External output (X32KFOUT in
the datasheet), at index 1,
- the Internal Oscillator, at index 2.

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.
