Hi alle, ich lese gerade das Datenblatt von LAN9500A http://ww1.microchip.com/downloads/en/DeviceDoc/00001875A.pdf. Da steht für den Pin VBUS_DET: > > For bus powered applications, this pin must be tied to VDD33IO. > > For self powered applications where the device is permanently attached to a host, VBUS_DET should be pulled to VDD33IO. </pre> Was bedeutet denn eigentlich "pulled to VDD33IO"? Etwas so was hier? <pre> VDD33IO | R | VBUS_DET -----|---- GND </pre>
