     * @group:       	4.1.9 FAST LINK-UP
     *
     * @description: 	Link up time is normally determined by the time it takes to complete auto-negotiation. Additional time may be added by
     * 					the auto MDI/MDI-X feature. The total link up time from power-up or cable connect is typically a second or more.
     * 					Fast Link-up mode significantly reduces 100BASE-TX link-up time by disabling both auto-negotiation and auto MDI/
     * 					MDI-X, and fixing the TX and RX channels. This mode is enabled or disabled by the LED2_1 strapping option. It is not
     * 					set by registers, so fast link-up is available immediately upon power-up. Fast Link-up is available at power-up only for
     * 					100BASE-TX link speed, which is selected by strapping the LED4_0 pin high. Fast Link-up is also available for 10BASE-
     * 					Te, but this link speed must first be selected via a register write.
     * 					Fast Link-up is intended for specialized applications where both link partners are known in advance. The link must also
     * 					be known so that the fixed transmit channel of one device connects to the fixed receive channel of the other device, and
     * 					vice versa. The TX and RX channel assignments are determined by the MDI/MDI-X strapping option on LED2_0.
     * 					If a device in Fast Link-up mode is connected to a normal device (auto-negotiate and auto-MDI/MDI-X), there will be no
     * 					problems linking, but the speed advantage of Fast Link-up will not be realized.
     * 					For more information on configuration straps, refer to Section 3.2.1, "Configuration Straps," on page 18.
