Functions
A resistor is connected between both terminals to from a ring
oscillator, or external reference signals are applied to OSC1.
For binary selection: this Terminal in Conjunction with SEL1, selects a Melody.
For direct selection: Selects Melody 2 and Controls Start and Stop of it’s
Performance.
Power Supply Terminal (0V).
Connects Resistor and Capacitor to add Envelope to Main Melody.
Connects Resistor and Capacitor to add Envelope to Accompaniment.
Output Terminal or Acoustic Signals that have not been Amplified.
3.0V to 5.0V Operating Voltage
