The Ethernet is compliant with the following standards:
● IEEE 802.3-2002 for Ethernet MAC
● IEEE 1588-2002 (就是1588v1)standard for precision networked clock synchronization
data sheet:
（http://www.st.com/internet/com/T ... HEET/CD00237391.pdf）
2.2.31 Ethernet MAC interface with dedicated DMA and IEEE 1588 support

Reference Manual和Data sheet矛盾 哪个为准呢？ |
