CHAPTER 4: PERIPHERAL CIRCUITS AND OPERATION (Sound Generator)
4.12 Sound Generator
4.12.1 Configuration of sound generator
The S1C6P466 has a built-in sound generator for generating buzzer signals.
Hence, generated buzzer signals (BZ) can be output from the BZ terminal.
Aside permitting the respective setting of the buzzer signal frequency and sound level to 8 stages, it
permits the adding of a digital envelope by means of duty ratio control. It also has a one-shot output
function for outputting key operated sounds.
Figure 4.12.1.1 shows the configuration of the sound generator.

4.12.2 Mask option
Polarity of the BZ signal output from the BZ terminal is fixed at positive polarity.
Figure 4.12.2.1 shows the output circuit configuration and the output waveform.

4.12.3 Control of buzzer output
The BZ signal generated by the sound generator is output from the BZ terminal by setting "1" for the
buzzer output enable register BZE. When "0" is set to BZE register, the output terminal goes low (VSS)
level.

Note: Since it generates a BZ signal that is out of synchronization with the BZE register, hazards may at
times be produced when the signal goes ON/OFF due to the setting of the BZE register.
