Systems and methods are disclosed for providing a temporarily modified output. A waveform control provides a control output that temporarily adjusts to an intermediate level between normal high and low levels during a first operating mode. The waveform control provides the control output to transition periodically between the high and low levels during a second operating mode. A delay network controls the waveform control to provide the output at the intermediate level for a duration during the first operating mode.
