I/O DESCRIPTION - Power supply pin (+). I Sound selection keys. These keys connect with internal pull-down resistors. The I sound output will be enabled when a key is connected to VDD. On other hands, I the sound output will be disabled if a key is N.C. or connected to GND. I When two or more keys are selected in the same time, the sound will be I generated in cycling sequence. According to the priority of the keys, the proirity of I S1~S6 li...
