I am looking at the Freescale MCP8260 processor.

For programming PINS you set values to some registers. I would like to use MII interface for Fast Ethernet for example. I can see the Dedicated PINS table and everything is fine. But TX_CLK and RX_CLK aren't at the table. Why are they missing? All other PINS exist (except from 2 that manual explains but says nothing why the clock pins aren't there). However there is a register that can be used to change the clock but why are they missing?

Is it possible A TDMA device to use the same clock for receiving and transmitting?

You specify which clocks are used for TX and RX in the CPM Multiplexing logic (Chapter 16 in the databook).
