@brief I2S clock configuration for PDM TX mode

Fields

sample_rate_hz: u32

< I2S sample rate, not suggest to exceed 48000 Hz, otherwise more glitches and noise may appear

clk_src: i2s_clock_src_t

< Choose clock source

mclk_multiple: i2s_mclk_multiple_t

< The multiple of MCLK to the sample rate

up_sample_fp: u32

< Up-sampling param fp

up_sample_fs: u32

< Up-sampling param fs, not allowed to be greater than 480

bclk_div: u32

< The division from MCLK to BCLK. The minimum value is I2S_PDM_TX_BCLK_DIV_MIN. It will be set to I2S_PDM_TX_BCLK_DIV_MIN by default if it is smaller than I2S_PDM_TX_BCLK_DIV_MIN
