SLAVE agreement description The agreement format is the same with IIC: Control command format START 55H+ACK COMMAND+ACK STOP; State information format START AAH+ACK DATA1+ACK+......+DATAn+ACK STOP; Agreement description ACK format: The host will set DATA bus high at the falling edge of CLK, and judge the state of DATA bus at the rising edge of CLK. Then it will set DATA low if its state is high and exit if its state is low. Data format: Sending interval of the control command is longer than 30ms; State information must be received continuously with interval time longer than 50ms. Function Stop after power on complete reading the toc Play the first music after power on complete reading the toc

MOS DEVICES OPERATE NOTES:
Electrostatic charges may exist in many things. Please take following preventive measures to prevent effectively the MOS electric circuit as a result of the damage which is caused by discharge: The operator must put on wrist strap which should be earthed to against electrostatic. Equipment cases should be earthed. All tools used during assembly, including soldering tools and solder baths, must be earthed. MOS devices should be packed in antistatic/conductive containers for transportation.
