 171 <p>Ethernet common definitions (Driver_ETH.h) </p>
 172 <p><b>Ethernet</b> is a networking technology for exchanging data packages between computer systems. Several microcontrollers integrate an Ethernet MAC (Media Access Control) data-link layer that interfaces to an Ethernet PHY (Physical Interface Transceiver).</p>
 173 <p>Wikipedia offers more information about the <a href="https://en.wikipedia.org/wiki/Ethernet" target="_blank"><b>Ethernet</b></a>.</p>
 174 <p><b>Block Diagram</b></p>
 175 <p>The Ethernet PHY connects typically to the Ethernet MAC using an MII (Media Independent Interface) or RMII (Reduced Media Independent Interface).</p>

 181 <p><b>Ethernet API</b></p>
 182 <p>The following header files define the Application Programming Interface (API) for the <b>Ethernet</b> interface:</p><ul>
 183 <li><b>Driver_ETH.h</b> : Common definitions of the Ethernet PHY and MAC part</li>
 184 <li><b>Driver_ETH_MAC.h</b> : API for the Ethernet MAC</li>
 185 <li><b>Driver_ETH_PHY.h</b> : API for the Ethernet PHY</li>
 186 </ul>
 187 <p>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. The driver implementation of the Ethernet PHY is a typical part of a <b>Network</b> Software Pack, since PHY is typically not integrated into the microcontroller.</p>
 188 <dl class="section note"><dt>Note</dt><dd>For parameters, the value marked with (default) is the setting after the driver initialization.</dd></dl>
 189 <p><b>Driver Functions</b></p>
 190 <p>The driver functions are published in the access struct as explained in <a class="el" href="theoryOperation.html#DriverFunctions">Common Driver Functions</a></p><ul>
 191 <li><a class="el" href="group__eth__mac__interface__gr.html#structARM__DRIVER__ETH__MAC">ARM_DRIVER_ETH_MAC</a> : access struct for <b>Ethernet MAC</b> driver functions.</li>
 192 <li><a class="el" href="group__eth__phy__interface__gr.html#structARM__DRIVER__ETH__PHY">ARM_DRIVER_ETH_PHY</a> : access struct for <b>Ethernet PHY</b> driver functions.</li>
 193 </ul>
 194 <p>Both drivers are used in combination and usually the Ethernet MAC provides a media interface to the Ethernet PHY. A typical setup sequence for the drivers is shown below:</p>
 195 <p><b>Example Code</b></p>
