            The REF_CLK is provided for both transmitted and received data
            in RMII mode. This clock signal is provided by the PHY and is
            typically derived from an external 25MHz crystal. Alternatively,
            a 50MHz clock signal generated by an external oscillator can be
            connected to pin REF_CLK. A third option is to connect a 25MHz
            clock to pin CLK_IN_OUT. So, the REF_CLK should be configured
            as input or output according to the actual circuit connection.
            If present, indicates that the REF_CLK will be configured as
            interface reference clock input when RMII mode enabled.
            If not present, the REF_CLK will be configured as interface
            reference clock output when RMII mode enabled.
            Only supported on TJA1100 and TJA1101.

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.
