				Transmit Disable:
				TX_DISABLE_0:3 outputs disable the Optical
				Module Interface transmitter. An external pull-up
				resistor usually resident in an optical module is
TX_DISABLE_0	AB3	Open	2.5 V	required for proper operation.
TX_DISABLE_1	AA7
		Drain
TX_DISABLE_2	AD16		CMOS	NOTE: These signals are multiplexed with the
		Output*
TX_DISABLE_3	AA14
				TXD[4]_n bits of the GMII Interface
				NOTE: *Dual-mode I/O
				Normal operation: Open drain output
				Boundary Scan Mode: Standard CMOS
				output
MOD_DEF_0	Y6			MOD_DEF_0:3 inputs determine when an
				Optical Module Interface is present.
MOD_DEF_1	AD10		2.5 V
		Input
MOD_DEF_2	W22		CMOS
				NOTE: These signals are multiplexed with the
MOD_DEF_3	T16
				RXD[4]_n bits of the GMII interface.
RX_LOS_0	AB5			RX_LOS_0:3 inputs determine when the Optical
				Module Interface receiver loses synchronization.
RX_LOS_1	AA11		2.5 V
		Input
RX_LOS_2	V19		CMOS
				NOTE: These signals are multiplexed with the
RX_LOS_3	T18
				RXD[6]_n bits of the GMII interface.
TX_FAULT_0	Y5			TX_FAULT_0:3 inputs determine an Optical
				Module Interface transmitter fault.
TX_FAULT_1	AC11		2.5 V
		Input
TX_FAULT_2	V20		CMOS
				NOTE: These signals are multiplexed with the
TX_FAULT_3	T17
				RXD[5]_n bits of the GMII Interface.
				Receiver Loss of Signal Interrupt.
				RX_LOS_INT is an open drain interrupt output to
				signal an RX_LOS condition.
		Open	2.5 V	NOTE: An external pull-up resistor is required
RX_LOS_INT	P19	Drain
			CMOS	for proper operation.
		Output*
				NOTE: *Dual-mode I/O
				Normal operation: Open drain output
				Boundary Scan Mode: Standard CMOS
				output
