     * @group:       	4.1 Physical Layer Transceiver (PHY)
	 *
     * @description:	Ports 1 through 5 include completely integrated triple-speed (10BASE-Te, 100BASE-TX, 1000BASE-T) Ethernet phys-
     * 					ical layer transceivers for transmission and reception of data over standard four-pair unshielded twisted pair (UTP), CAT-
     * 					5 or better Ethernet cable.
     * 					The device reduces board cost and simplifies board layout by using on-chip termination resistors for the four differential
     * 					pairs, eliminating the need for external termination resistors. The internal chip termination and biasing provides signifi-
     * 					cant power savings when compared with using external biasing and termination resistors.
     * 					The device can automatically detect and correct for differential pair misplacements and polarity reversals, and correct
     * 					for propagation delay differences between the four differential pairs, as specified in the IEEE 802.3 standard for
     * 					1000BASE-T operation.
