K60D100M unused ethernet pins

Hi Everyone,

 

I am using the TWR-K60D100M and TWR-SER schematic as a guideline for moving our system to a dedicated PCB. However, I am confused by looking at page 8 of the electrical schematic for the TWR-K60D100M: Many of the pins from A12-A20 and B12-B20 do not make it back to the MCU. Most interestingly, TXCLK and RXCLK don't get bussed back...this seems like it will not function.

 

Does anyone have some insight for this? Sorry if this is a really obvious question. I am new to the PCB field, Ethernet, and the Tower System! Any help is very appreciated.
