4.5. IEEE 1588v2 PTP
The Ethernet Subsystem can be configured to support Precision Time Protocol (PTP) which provides 1588 Precision Time Protocol timestamp information as defined in the IEEE 1588-2008 Precision Clock Synchronization Protocol for Networked Measurement and Control System Standard. 1588 PTP logic generates timestamp information for transmitted and received packets. The generated timestamps represent the time when the first bit after the Start of Frame Delimiter (SFD) byte crosses the FPGA serial pins (Medium Dependent Interface, MDI).
