MPC8572EAMC Functional Description
5.2
The MPC8572E supports up to four Gigabit Ethernet ports. All four ports are configured in the SGMII
mode to ease routing and reduce power on the MPC8572EAMC. As shown in
88E1112 devices are used to provide the physical interfaces for the SGMII front panel Ethernet
connectivity on the MPC8572EAMC board using eTSEC1 and eTSEC2. A further two 88E1112 devices
are used to generate SGMII Ethernet functionality on the ports 0 and 1 of the rear AdvancedMC edge
connector using eTSEC3 and eTSEC4 on the MPC8572E.
After reset, the initial power on status of each PHY is determined via six configuration pins:
CONFIG[0:5], as shown in
address, clocking etc.
