Abstract
An integrated circuit device having an output driver circuit and a control circuit. The output driver circuit outputs a first signal having a signal level according to a control value. The control circuit is coupled to receive the first signal from the output driver and adjusts the control value by a first increment until a transition event is detected. After the transition event is detected, the control circuit adjusts the control value by a second increment, the second increment being smaller than the first increment.
