The host can send a packet to be transmitted on an Ethernet port that will generate a time synchronization event. The host sets the TSTAMP_EN bit and sends the DOMAIN, MESSAGE_TYPE, and SEQUENCE_ID in the additional control information that resides in the protocol specific section of the descriptor that is transmitted to the CPSW. An event is then generated and placed on the event FIFO once the packet is transmitted. Host events allow the user to timestamp exactly when a software generated packet exits the device.
