Detailed Description

I2S Hardware attributes.

intPriority is the I2S peripheral's interrupt priority, as defined by the RTOS kernel. This value is passed unmodified to HwiP_construct().

A sample structure is shown below:

const I2SLPF3_HWAttrs i2sHWAttrs[CONFIG_TI_DRIVERS_I2S_COUNT] = {
    {
       .afclkSrc     =  I2SLPF3_AFCLK_SRC_CLKAF,
       .afoscFreq    =  PowerLPF3_AFOSC_FREQ_98P304MHZ,
       .sd1Pin       =  CONFIG_I2S_ADI,
       .sd1PinMux    =  GPIO_MUX_PORTCFG_PFUNC4,
       .sd0Pin       =  CONFIG_I2S_ADO,
       .sd0PinMux    =  GPIO_MUX_PORTCFG_PFUNC4,
       .sckPin       =  CONFIG_I2S_BCLK,
       .sckPinMux    =  GPIO_MUX_PORTCFG_PFUNC1,
       .cclkPin      =  CONFIG_I2S_CCLK,
       .cclkPinMux   =  GPIO_MUX_PORTCFG_PFUNC1,
       .wsPin        =  CONFIG_I2S_WCLK,
       .wsPinMux     =  GPIO_MUX_PORTCFG_PFUNC1,
       .intPriority  =  ~0,
    },
};
