Detailed Description

PDMCC26XX_I2S Audio Pin 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_AudioPinConfig PDMCC26XX_I2Sobjects[] = {
        PDMCC26XX_I2S_ADUsageDisabled,
        0,
        0,
        0,
        0,
        PDMCC26XX_I2S_ADUsageInput,
        0,
        1,
        2,
        I2S_MONO_MODE
};
