回路。A frequency divider that has a reference oscillator and divides its output, a serial port that uses the divided signal as a clock and can vary the output signal by changing the output conditions and data, and a communication output on its output. This speaker drive circuit has a switch element for switching the speaker drive output and the speaker drive output, and is characterized in that the tone of the speaker can be varied by a signal from a serial port, and the communication output and the speaker output can be shared.
