Function
(1) When the external clock input mode is selected by mask option:
Enter square waves of 32.768KHz or 47.520KHz to the OSC1 pin as the reference signal source.
(2) When the integrated CR oscillation is selected by mask option:
When using an external "R", insert a resistor between the OSC1 and OSC2 to adjust the oscillation
frequency by the resistance of the resistor.
When using integrated CR, keep the OSC1 and OSC2 open.
Negative supply pin or grounding pin
This is the IC test input pin.
When "High" level is input, the device goes into working mode to control starting and stopping of the
performance in accordance with the performance method being designated by the option.
Melody 1 and melody 2 can be selected in the binary code order by entering "0" or "1" into this pin.
(1) When "changing the melody midway during performance - not possible" is selected by mask op-
tion:
After going into the working mode on input of "High" to the MT pin, the input level of either "Low" or
"High" which was applied to the SEL pin just before starting performance is adopted and the per-
forming melody shall not thereafter change even if the input level to the SEL pin changes.
(2) When "changing the melody midway during performance - possible" is selected by mask option:
Each time the level of the input to the SEL pin changes during a working mode, the melody
changes and, when changing the melody, performance shall be resumed from the beginning of the
melody.
This pin outputs square wave signals.
With the audio signals, the key melody and accompaniment, respectively, are attenuated under a cer-
tain time constant and respective audio outputs of the key melody and accompaniment are mixed by the
mixing resistor before being output.
This pin should therefore be connected to the input pin of a pre-amp via a variable resistor for volume
control, coupling-capacitor, etc.
