Description
-----------

The Standard Microsystems Corporation (SMSC) / Microchip EMC14xx chips
contain up to eight temperature sensors. EMC14x2 support two sensors
(one internal, one external). EMC14x3 support three sensors (one internal,
two external), EMC14x4 support four sensors (one internal, three external),
and EMC14x8 support eight sensors (one internal, seven external).

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.
