9.14.1 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 DS33R11 in MII mode are shown in the following
two figures.
In DCE Mode, the DS33R11 transmitter is connected to an external receiver and DS33R11 receiver is connected
to an external MAC transmitter. The selection of DTE or DCE mode is done by the hardware pin DCEDTES.
