15.3.6.5 IEEE 1588-2008 Advanced Timestamps
In addition to the basic timestamp features mentioned in IEEE 1588-2002 Timestamps, the Ethernet Controller supports the following advanced timestamp features defined in the IEEE 1588-2008 standard:
- Supports the IEEE 1588-2008 (version 2) timestamp format.
- Provides an option to take snapshot of all frames or only PTP type frames.
- Provides an option to take snapshot of only event messages.
- Provides an option to take the snapshot based on the clock type: ordinary, boundary, end-to-end, and peer-to-peer.
- Provides an option to select the node to be a master or slave clock.
- Identifies the PTP message type, version, and PTP payload in frames sent directly over Ethernet and sends the status.
- Provides an option to measure subsecond time in digital or binary format.
