说明：  1音频信号从J10（MIC IN）进去，编码后送dsPIC控制器，dsPIC接收直接送回SI3000解码从J11（SPK OUT）输出 DCI采用中断接收数据 SI3000工作在SLAVE从模式（由dsPIC提供SCK）
(1 audio signal from the J10 (MIC IN) into the coding dsPIC controller evacuation, dsPIC decoder to receive directly from the SI3000 back to J11 (SPK OUT) output DCI used SI3000 interrupt the work of receiving data from the SLAVE mode (by the dsPIC provide SCK))
