 188 <p>Driver API for Ethernet PHY Peripheral (Driver_ETH_PHY.h) </p>
 189 <p>The following section describes the Ethernet PHY Interface as defined in the Driver_ETH_PHY.h header file.</p>
 190 <p>The Driver_ETH_PHY.h contains two #defines that are used to configure the connection between the PHY and the microcontroller device:</p><ul>
 191 <li><code>ETH_PHY_NUM</code> and</li>
 192 <li><code>ETH_PHY_ADDR</code> </li>
 193 </ul>
 194 <p>Usually, the Serial Management Interface (<b>SMI</b>) (using MDC and MDIO) is used to access the PHY’s internal registers to read the state of the link (up/down), duplex mode, speed, and to restart auto-negotiation etc. SMI is a serial bus, which allows to connect up to 32 devices. Devices on the bus are accessed using a 5-bit device address. A default device address is hardware configurable by pin-strapping on the device (some pins are sampled when a reset is asserted or at power-up).</p>
 195 <p>The device’s internal weak pull-up or pull-down resistors define a default device address. This address can be changed by connecting strong pull-up or pull-down resistors externally. In this case, the <code>ETH_PHY_ADDR</code> needs to be defined by the user.</p>
 196 <p>If a microcontroller device offers more than one Ethernet PHY driver, the user needs to set the correct <code>ETH_PHY_NUM</code> in his application. </p>

 211 <p>Each instance of an Ethernet PHY provides such an access struct. The instance is identified by a postfix number in the symbol name of the access struct, for example:</p><ul>
 212 <li><b>Driver_ETH_PHY0</b> is the name of the access struct of the first instance (no. 0).</li>
 213 <li><b>Driver_ETH_PHY1</b> is the name of the access struct of the second instance (no. 1).</li>
 214 </ul>
 215 <p>A configuration setting in the middleware allows connecting the middleware to a specific driver instance <b>Driver_ETH_PHY<em>n</em></b>. The default is <span class="XML-Token">0</span>, which connects a middleware to the first instance of a driver. </p>
