Ethernet Enable MCF52235

I have the M52235EVB running and I am getting a clock pulse that I can detect from the microcontroller to the PHY pins, 70,71,73 & 74. (I am using the 112 pin flat pack). This signal is then passed to the Pulse H2019 transformer which is then going to the ethernet port.
 
I am testing my circuit (I designed) and I do not get that clock pulse coming from the same pins on my microcontroller (MCF55235).
 
Is there an ethernet enable I am missing somewhere? I am not doing a POE application.
 
Any help would be appreciated.
