PIN DESCRIPTION
Pin. No. Pin Name Pull-Down Resistor Functions
1 OSC1 - A resistor is connected between both terminals to from a ring
2 OSC2 - oscillator, or external reference signals are applied to OSC1.
3 TST2 Provided LSI Test Input/Output.
4 MT Provided For binary selection: Controls Start and Stop of Performance.
For direct selection: Selects Melody 1 and Controls Star t and Stop of it’s Performance.
5 SEL2 Provided For binary selection: this Terminal in Conjunction with SEL1, selects a Melody.
For direct selection: Selects Melody 3 and Controls Start and Stop of it’s Performance.
