12.7 RMDIO (Remote MDIO Access) Extended Link Monitoring
The RMDIO Extended Link Monitoring feature allows the local device on a fiber link to remotely access the MDIO
register contents of the device at the far end of the link. Both read and write transactions to the remote PHY regis-
ter space are supported.
Once a RMDIO read request is initiated, Device A will send a RMDIO request message, Device B will then fetch
the specified MDIO register content and insert it inside a RMDIO response message. Device A will then extract the
data from the response message and place the result in Register 3.CC0Ch.
