There are three MCU on my board, they are MPC5748G, MPC5777M(MCU0) and MPC5777M(MCU1) . They are interconnected through MPC5748G ethernet switch module. MPC5777M(MCU0) and MPC5777M(MCU1) are connected to MAC-NET0 and MAC-NET1, then I want to ask the follow questions.
1. Can MCU0 and MCU1 communicate through MPC5748G ethernet switch module ?
2. Can MPC5748G connect to MPC5777M through MII interface without PHY ?
