I compared the FMCMOTCON2 schematic to the FMCMOTCON1 schematic and there the pull-up is connected to MDIO indeed. Subject: MDIO History1 Management Data Input/Output, or MDIO, is a two-wire serial control bus used to manage physical-layer devices (PHYs) in media access controllers (MACs) inside Gigabit Ethernet equipment which requires accessing and modifying their var ious registers. It is a function of the Regulator to publish the details of enforcement action. See the DPAA2 User Manual for details about MDIO registers block. extended register access, therefore requires stubs to fail the read register method and do nothing for the write register method when libphy attempts to read and/or configure Energy Efficient Ethernet features in PHYS that do support those features. SPI is a cousin of I2C with similar applications. ® Intel IXF1104 4-Port Gigabit Ethernet Media Access Controller 8.
