Sound selection keys. These keys connect with internal pull-down resistors. The sound output wiil be enabled when a key is connected to VDD. On other hands, the sound output will be disabled if a key is N.C. or connected to GND. 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, the proirity of S1~S6 list below : S1>S2>S6>S4>S5>S3. 8 GND - Power supply pin (-). 9 INI I An internal pull-up resistor.
