Abstract: A semiconductor device includes two power-on reset (POR) circuits having different response characteristics to a change in power voltage in generating and outputting a reset signal by detecting a change in voltage value of the power voltage, and a selector. The selector selects a reset signal outputted from one of the two POR circuits based on an inputted selection control signal, and outputs the selected signal as a reset signal.

Abstract: An automatic audio signal level adjustment circuit is capable of automatically adjusting a level of an input audio signal within a specific range. The automatic audio signal level adjustment circuit includes an amplitude adjustment determining unit and an amplitude adjusting unit. The amplitude adjustment determining unit is configured to generate an amplitude reduction instruction when the level is greater than a first reference value, and an amplitude augmentation instruction when the level is small than a second reference value. The amplitude adjusting unit is configured to output an output audio signal having an amplitude reduced from that of the input audio signal upon the amplitude reduction instruction, and an output audio signal having an amplitude augmented from that of the input audio signal upon the amplitude augmentation instruction. Further, the amplitude adjusting unit is configured to output an output audio signal equal to the input audio signal upon no instruction.
