      Array of resistance values in Ohms for the external Rfs resistors
      connected to the FS pins. These values determine the full-scale
      output current. The actual resistance depends on the chip variant
      and specific hardware design requirements.

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.
