i2s_pdm_tx_slot_config_t struct

I2S sample data bit width (valid data bits per sample), only support 16 bits for PDM mode.

I2S slot bit width (total bits per slot), only support 16 bits for PDM mode.

Set mono or stereo mode with I2S_SLOT_MODE_MONO or I2S_SLOT_MODE_STEREO For PDM TX mode, mono means the data buffer only contains one slot data, Stereo means the data buffer contains two slots data.

Slot mask to choose left or right slot.

Sigma-delta filter prescale.

Sigma-delta filter scaling value.

High pass filter scaling value.

Low pass filter scaling value.

Sinc filter scaling value.
