  Part numbers as follows: mcp4ABC-XXX where
  A =   5 (1 wiper), 6 (2 wipers)
  B =   3 (7-bit, volatile), 4 (7-bit, non-volatile),
        5 (8-bit, volatile), 6 (8-bit, non-volatile),
  C:    1 (potentiometer), 2 (rheostat)
  XXX = 502 (5 kOhms), 103 (10 kOhms), 503 (50 kOhms), 104 (100 kOhms)

    enum:
        # Ordering reflects part number + range, so 502 < 103 etc

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.
