Hi, ich habe solche Beschreibungen für Ports im AT90CAN128 gelesen. The Port A output buffers have symmetrical drive characteristics with both sink and source capability. As inputs, Port A pins that are externally pulled low will source current if the pull-up resistors are activated. Was versteht man unter dem Begriff < symmetrical drive characteristics >? Was bedeutet der zweite Satz? Ciao BTfan
