     * @group:       	4.6 IEEE 1588 Precision Time Protocol
     *
     * @description: 	The IEEE 1588 precision time protocol (PTP) provides a method for establishing time synchronization across nodes in
     * 					a network. The device supports V2 (2008) of the IEEE 1588 PTP specification and can be programmed as either an
     * 					end-to-end (E2E) or peer-to-peer (P2P) transparent clock (TC) between ports. In addition, the host port can be pro-
     * 					grammed as either a slave or master ordinary clock (OC) port. Ingress timestamp capture, egress timestamp recording,
     * 					correction field update with residence time and link delay, delay turn-around time insertion, egress timestamp insertion,
     * 					and checksum update are supported. PTP frame filtering is implemented to enhance overall system performance. Delay
     * 					adjustments are implemented to fine tune the synchronization. Versatile event trigger outputs and timestamp capture
     * 					inputs are implemented to meet various real time application requirements through the GPIO_1 pin.
     * 					The key features of the IEEE 1588 implementation are:
     * 					• Either one-step or two-step event message format
     * 					• Implementation of precision time clock per specification
     * 					- Upper 16 bits of the second clock not implemented
     * 					• Both E2E and P2P TC
     * 					• Both slave and master OC
     * 					• PTP multicast and unicast addressing
     * 					• Transport of PTP over IPv4/IPv6 UDP and IEEE 802.3/Ethernet
     * 					• Precision time stamping of input signal on the GPIO_1 pin
     * 					• Creation and delivery of clock, pulses, or other unique serial bit stream on the GPIO_1 pin with respect to the pre-
     * 					cision time clock time.
     * 					• IEEE 802.1AS gPTP supported
     * 					IEEE 1588 defines two essential functions: The measurement of link and residence (switching) delays by using the
     * 					Delay_Req/Resp or Pdelay_Req/Resp messages, and the distribution of time information by using the Sync/Follow_Up
     * 					messages. The 1588 PTP event messages are periodically sent from the grandmaster in the network to all slave clock
     * 					devices. Link delays are measured by each slave node to all its link partners to compensate for the delay of PTP mes-
     * 					sages sent through the network.
     * 					All PHY ports must be operating at 100 Mbps or 1 Gbps when implementing IEEE 1588. It is not compatible with 10
     * 					Mbps.
