CC1310的I2S是怎么设置的啊？

    PRCMDomainEnable(PRCM_DOMAIN_RFCORE);
    PRCMDomainEnable(PRCM_DOMAIN_SERIAL);
    PRCMDomainEnable(PRCM_DOMAIN_PERIPH);
    PRCMDomainEnable(PRCM_DOMAIN_VIMS);
    PRCMDomainEnable(PRCM_DOMAIN_SYSBUS);
    PRCMDomainEnable(PRCM_DOMAIN_CPU);

    PRCMPowerDomainOn(PRCM_DOMAIN_RFCORE);
    PRCMPowerDomainOn(PRCM_DOMAIN_SERIAL);
    PRCMPowerDomainOn(PRCM_DOMAIN_PERIPH);
    PRCMPowerDomainOn(PRCM_DOMAIN_VIMS);
    PRCMPowerDomainOn(PRCM_DOMAIN_SYSBUS);
    PRCMPowerDomainOn(PRCM_DOMAIN_CPU);

    PRCMPeripheralRunEnable(PRCM_PERIPH_I2S);
    PRCMLoadSet();
    PRCMPeripheralRunEnable(PRCM_PERIPH_UDMA);
    PRCMLoadSet();

    PRCMAudioClockEnable();
    PRCMAudioClockConfigSet(PRCM_WCLK_DUAL_PHASE|PRCM_WCLK_NEG_EDGE,I2S_SAMPLE_RATE_16K);
//    PRCMAudioClockConfigSetOverride(PRCM_WCLK_SINGLE_PHASE|PRCM_WCLK_NEG_EDGE,48000000,16000,1000);
    PRCMLoadSet();

    IOCPortConfigureSet(IOID_4,IOC_PORT_MCU_I2S_AD0,IOC_STD_OUTPUT);
    IOCPortConfigureSet(IOID_5,IOC_PORT_MCU_I2S_AD1,IOC_STD_INPUT);
    IOCPortConfigureSet(IOID_8,IOC_PORT_MCU_I2S_WCLK,IOC_STD_OUTPUT);
    IOCPortConfigureSet(IOID_9,IOC_PORT_MCU_I2S_BCLK,IOC_STD_OUTPUT);
    IOCPortConfigureSet(IOID_10,IOC_PORT_MCU_I2S_MCLK,IOC_STD_OUTPUT);

    uDMAEnable(UDMA0_BASE);

    I2SAudioFormatConfigure(I2S0_BASE,I2S_MEM_LENGTH_16|I2S_NEG_EDGE|I2S_DUAL_PHASE_FMT|I2S_WORD_LENGTH_16,1);
    I2SChannelConfigure(I2S0_BASE,I2S_LINE_OUTPUT|I2S_STEREO_MODE,I2S_LINE_INPUT|I2S_STEREO_MODE);//??
    I2SClockConfigure(I2S0_BASE,I2S_INT_WCLK|I2S_NORMAL_WCLK);
    I2SBufferConfig(I2S0_BASE,(uint32_t)InBufBaseA,(uint32_t)OutBufBaseA,200,200);//??

//
//

    I2SIntRegister(I2S0_BASE,i2sinterrupt);
    I2SIntEnable(I2S0_BASE,I2S_INT_ALL);

    I2SEnable(I2S0_BASE);
    I2SPointerSet(I2S0_BASE,false,OutBufBaseA);
    I2SPointerUpdate(I2S0_BASE,false);

有大神会吗？这都搞了好几天了，哎
