Internal means there is not a standard bus between the MAC and the PHY, something proprietary is being used to embed the PHY in the MAC. If you are using RMII or RGMII, then it is not internal, in that as standard bus is being used. It does not matter if that bus is not available external to the SoC, it still exists. Andrew
