MAC INTERFACES		RGMII
TX_CLK	30		O	MII TRANSMIT CLOCK: TX_CLK is a continuous clock signal driven by the PHY during 10 Mbps or 100 Mbps MII mode. TX_CLK clocks the data or error out of the MAC layer and into the PHY.
TX_CLK	30		O	The TX_CLK clock frequency is 2.5 MHz in 10BASE-Te and 25 MHz in 100BASE-TX mode.
