VCC Power
S1 Sound selection keys. These connects
S2 with internal pull-down Resistor. The
S3 sound output wiil be enabled when a key
S4 is connected to VDD, on other hands, the
S5 sound output will be disabled if a key is
S6 N.C. or connected to GND(ground).
When two or more keys are selected in
the same time, the sound will be
generated in cycling sequence, according
to the priority of the keys.

S1>S2>S6>S4>S5>S3
GND Ground
INI An internal pull-up resistor. Might disable
BZ1, BZ2 when connected to GND.
