Channel 1 is set when the
CH
pin is "H" level, channel 2 is set when CH is "L" level. Once a command
is set, it is maintained as both channels until another command is input. The condition of each channel
is set by I4 to I0. Three conditions can be set: 1) to 3).
1) Setting the Number of Repeats
The number of repeats is set by the I3 and I2 pins, and four types can be selected: 1, 2, 4 and infinite.
A stop code must be input to stop voice when infinite repeat is selected. Table 6.5 shows the
relationship between I3 and I2 pins, and the number of repeats.

2) Sound Volume Smoothing During Repeat
If "I4" is set to a "1", sound volume during repeat is automatically attenuated from 1 to 1/2, 1/4 and
1/8 (fade-out function). This smoothing, however, is effective only when 2, 4 or infinite is selected
for the repeat setting.
If infinite is selected, voice is played, remaining at 1/8 sound volume after attenuating from 1, 1/2,
1/4 and to 1/8. If the initial sound volume setting is other than 1, the sound volume attenuates from
that value in 1/2 units, stopping at 1/8.
3) Setting Sound Volume
Voice volume can be changed in four steps if voice is played overlapping in channel synthesis. The
sound volume is set at I1 and I0 pins.
Table 6.6 shows the relationship between I1, I0 pins and sound volume settings.
