CHAPTER 4: PERIPHERAL CIRCUITS AND OPERATION (Sound Generator)
4.11 Sound Generator
4.11.1 Configuration of sound generator
The S1C60N13 Series outputs buzzer signals (BZ, BZ) to drive the piezoelectric buzzer.
The frequency of the buzzer signal is software-selectable from eight kinds of demultiplied fOSC1. Further,
a digital envelope can be added to the buzzer signal through duty ratio control.
Figure 4.11.1.1 shows the sound generator configuration. Figure 4.11.1.2 shows the sound generator
timing chart.
