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.

INT / PWDN	60	44	I/O, PU	INTERRUPT / POWER DOWN:
				The default function of this pin is POWER DOWN.
				POWER DOWN: Asserting this signal low enables the Power Down mode of operation. In this mode, the device will power down and consume minimum power. Register access will be available through the Management Interface to configure and power up the device.
