5 PERIPHERAL CIRCUITS AND THEIR OPERATION (Sound Generator)
5.12 Sound Generator
5.12.1 Configuration of sound generator
The S1C88816 has a built-in sound generator for
generating buzzer signals.
The buzzer signals (BZ and BZ) generated by this
circuit are output from the R50 and R51 output port
terminals. Furthermore, the melody output
terminals (MOUT and MOUT) can be used for
output. See "5.13 Melody Generator" for using the
melody output terminals.
Aside permitting the respective setting of the
buzzer signal frequency and sound level (duty
adjustment) 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 5.12.1.1 shows the configuration of the
sound generator.

In the S1C88816, the R51 output port can be
configured as the BZ (BZ inverted signal) output
port by mask option. The description for the BZ
output in this section assumes that the R51 output
specification is set to the BZ output.
5.12.3 Control of buzzer output
The BZ signal can be output from the R50 output
port terminal. Furthermore, the R51 output port
terminal can be used to output the BZ signal (BZ
inverted signal) by mask option.

Fig. 5.12.3.1 Configuration of R50 and R51
The output control for the buzzer signal generated by
the sound generator is done by the buzzer output
control register BZON, one-shot buzzer trigger bit
BZSHT and one-shot buzzer forced stop bit BZSTP.
When "1" is set to BZON or BZSTP, the R50 goes
LOW (VSS) and the R51 goes HIGH (VDD).
To output the buzzer signal, "0" must always be set
for the data register R50D. The data register R51D
does not affect the BZ output.
Figure 5.12.3.2 shows the output waveform of the
buzzer signal.
Fig. 5.12.3.2 Buzzer output waveform
Note: Since the buzzer signal is generated asyn-
chronously from the registers BZON, BZSHT
and BZSTP, when the signal is turned ON or
OFF by the register settings, a hazard of a
1/2 cycle or less is generated.
