Function Blocks Description
PHY (Physical Layer Device)
Completely standardized physical layer device for the
functions of each device in the network.
EEPROM Stores the MAC address.
The physical layer device, the lowest layer of the OSI reference model, refers to
the physical components of the network: cables, connectors, and so on. OSI, the
Operating Standard Interface, is a framework upon which networking standards are
arranged. It is commonly diagramed as a layered cake.
