Detailed Description

PDMCC26XX_I2S Audio Clock configuration.

These fields are used by the driver to set up the I2S module

A sample structure is shown below (single PDM microphone):

const PDMCC26XX_I2S_AudioClockConfig PDMCC26XX_I2Sobjects[] = {
        16, // Word clock division
        PDMCC26XX_I2S_SampleEdge_Negative,
        PDMCC26XX_I2S_WordClockPhase_Dual,
        PDMCC26XX_I2S_ClockSource_Inverted,
        PDMCC26XX_I2S_WordClockSource_Int,
        47, // Bit clock division
        0, // Reserved
        PDMCC26XX_I2S_BitClockSource_Int
        6, // Master clock division
};

Field Documentation

uint16_t PDMCC26XX_I2S_AudioClockConfig::wclkDiv

I2S Word Clock divider override

uint16_t PDMCC26XX_I2S_AudioClockConfig::sampleOnPositiveEdge

uint16_t PDMCC26XX_I2S_AudioClockConfig::wclkPhase

I2S Word Clock Phase(PDMCC26XX_I2S_WordClockPhase_Dual, PDMCC26XX_I2S_WordClockPhase_Single or PDMCC26XX_I2S_WordClockPhase_UserDefined)

uint16_t PDMCC26XX_I2S_AudioClockConfig::wclkInverted

I2S Invert Word Clock (PDMCC26XX_I2S_ClockSource_Inverted or PDMCC26XX_I2S_ClockSource_Normal)

uint16_t PDMCC26XX_I2S_AudioClockConfig::wclkSource

I2S Word Clock source (PDMCC26XX_I2S_WordClockSource_Ext or PDMCC26XX_I2S_WordClockSource_Int)

uint16_t PDMCC26XX_I2S_AudioClockConfig::bclkDiv

I2S Bit Clock divider override

uint16_t PDMCC26XX_I2S_AudioClockConfig::reserved

Reserved bit field

uint16_t PDMCC26XX_I2S_AudioClockConfig::bclkSource
