    device 需要先写入SDTAC 启动寄存器写入才可以对寄存器进行操作
    在此之前需要检查PWDN以及Reset引脚的状态是否为 高
    在操作完寄存器后，需要发送RDATAC 才能连续 读取数据
    bsp_lpspi 的接口函数如下：
    Lpspi_Write(uint8_t datasize,uint8_t *data);
    Lpspi_Read(uint8_t datasize,uint8_t *data,uint8_t *Rxdata);
    注意：
        Lpspi的时序并不一定满足ADX516的配置，以下配置经过验证

        lpspi_master_config_t config;
        LPSPI_MasterGetDefaultConfig(&config);
        config.whichPcs=kLPSPI_Pcs0;
        config.baudRate=50000;
        config.betweenTransferDelayInNanoSec = 1000000000 /500;
        config.pcsToSckDelayInNanoSec=1000000000 /500;
        config.lastSckToPcsDelayInNanoSec=1000000000 /500;
        config.cpha=kLPSPI_ClockPhaseSecondEdge;
        LPSPI_MasterInit(LPSPI3, &config, LPSPI3_CLOCK_FREQ);
