description:
The Microchip PIT64B is a 64-bit periodic interval timer used in
several modern Microchip ARM SoCs including SAM9X60, SAM9X7 and
SAMA7D65 families. It provides extended timing range, flexible
clock selection and supports both periodic and one-shot interrupt
generation modes.

- 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.
