A typical setup sequence for the drivers is shown below: ARM_DRIVER_ETH_PHY : access struct for Ethernet PHY driver functions.īoth drivers are used in combination and usually the Ethernet MAC provides a media interface to the Ethernet PHY.ARM_DRIVER_ETH_MAC : access struct for Ethernet MAC driver functions.The driver functions are published in the access struct as explained in Common Driver Functions Note For parameters, the value marked with (default) is the setting after the driver initialization. The driver implementation of the Ethernet PHY is a typical part of a Network Software Pack, since PHY is typically not integrated into the microcontroller. The driver implementation of the Ethernet MAC is a typical part of a Device Family Pack (DFP) that supports the peripherals of the microcontroller family. Driver_ETH_PHY.h : API for the Ethernet PHY.Driver_ETH_MAC.h : API for the Ethernet MAC.Driver_ETH.h : Common definitions of the Ethernet PHY and MAC part.The following header files define the Application Programming Interface (API) for the Ethernet interface: The Ethernet PHY connects typically to the Ethernet MAC using an MII (Media Independent Interface) or RMII (Reduced Media Independent Interface).īlock Diagram of a typical Ethernet Interface Wikipedia offers more information about the Ethernet. Several microcontrollers integrate an Ethernet MAC (Media Access Control) data-link layer that interfaces to an Ethernet PHY (Physical Interface Transceiver).
