First and second counter circuits output a signal based on a trigger signal and a clock signal respectively. A selection circuit selects first to fourth signals as the trigger signal, the clock signal, the trigger signal and the clock signal. In a first output mode, an output circuit outputs signals exhibiting normal-phase and reversed-phase PWM waveforms based on both of the signals of the first and second counter circuits. In a second output mode, the output circuit outputs signals that are each based only on either of the signals of the first and second counter circuits. |
