8.13.1 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 DS33Z11 in MII mode are shown in the
following 2 figures.
In DCE Mode, the DS33Z11 transmitter is connected to an external receiver and DS33Z11 receiver is connected
to an external MAC transmitter. The selection of DTE or DCE mode is done by the hardware pin DCEDTES.
