9.12.1 DTE and DCE Mode
The Ethernet MII/RMII port can be configured for DCE or DTE Mode. When the port is configured for the DTE
Mode it can be connected to an Ethernet PHY. In DCE mode, the port can be connected to MII/RMII MAC devices
other than an Ethernet PHY. The DTE/DCE connections for the device in MII mode are shown in the following two
figures.
In DCE Mode, the transmitter is connected to an external receiver and the receiver is connected to an external
MAC transmitter. The selection of DTE or DCE mode is done by the hardware pin DCEDTES.
