5 PERIPHERAL CIRCUITS AND THEIR OPERATION (Output Ports)
Since the FOUT signal is generated asynchronously
from the register FOUTON, when the signal is
turned ON or OFF by the register settings, a hazard
of a 1/2 cycle or less is generated.
Figure 5.5.5.4 shows the output waveform of the
FOUT signal.

In order for the S1C88816 to drive an external
buzzer, the BZ signal (sound generator output) can
be output from the output port terminal R50.
Furthermore, the R51 output port terminal can be
used to output the BZ signal (BZ inverted signal).
The configuration of the output ports R50 and R51
is shown in Figure 5.5.5.5.

Fig. 5.5.5.5 Configuration of R50 and R51
The output control for the BZ (BZ) signal is done by
the registers BZON, BZSHT and BZSTP. When you
set "1" for the BZON or BZSHT, the BZ (BZ) signal
is output from the output port terminal R50 (R51).
When "0" is set for the BZON or "1" is set for the
BZSTP, the R50 goes LOW (VSS) and the R51 goes
HIGH (VDD).
To output the BZ signal, "0" must always be set for
the data register R50D. The data register R51D does
not affect the BZ output.
The BZ (BZ) signal is generated by the sound
generator. With respect to control of frequency and
envelope, see "5.12 Sound Generator".
Since the BZ (BZ) signal is generated asynchro-
nously from the registers BZON, BZSHT and
BZSTP, when the signal is turned ON or OFF by
setting the registers, a hazard of a 1/2 cycle or less
is generated.
Figure 5.5.5.6 shows the output waveform of the BZ
(BZ) signal.

s MOUT and MOUT outputs
MOUT and MOUT are the output ports dedicated
to direct driving an external piezoelectric buzzer
with the melody signal. These ports are fixed at
complementary output and cannot be set into high-
impedance state. Also data register is not available.
At initial reset, the MOUT and MOUT terminals go
HIGH.
See "5.13 Melody Generator" for melody output.
