Wake up event
Precision Time Protocol (IEEE1588) : What is it • It is a protocol designed to synchronize real-time clocks of the devices of a network • Synchronization is done with the most accurate clock found in a packet-based network: called the Grand Master Clock. • Accuracy is Sub-µsecond
– Media Independent Interface (MII) – Reduced Media Independent Interface (RMII)
• Integrated DMA controller • Hardware support of IEEE 1588 • Ethernet wakeup event
