Most ESCs with MII/RMII ports use the MII management interface for communication with the Ethernet PHYs. Most ESCs do not use the management interface for link detection or configuration of link modes. For link detection, it is recommended that the ESC use a separate signal (LINK_MII). The MII management interface can be used by the EtherCAT master – or the local MCU. Enhanced MII link detection uses the management interface for restarting auto-negotiation after communication errors occurred.
On this ESC, it is possible to make use of the MII management interface for link detection and PHY configuration.
