@brief I2S clock configuration for TDM mode

Fields

sample_rate_hz: u32

< I2S sample rate

clk_src: i2s_clock_src_t

< Choose clock source, see soc_periph_i2s_clk_src_t for the supported clock sources. selected I2S_CLK_SRC_EXTERNAL (if supports) to enable the external source clock inputted via MCLK pin, please make sure the frequency inputted is equal or greater than sample_rate_hz * mclk_multiple

ext_clk_freq_hz: u32

< External clock source frequency in Hz, only take effect when clk_src = I2S_CLK_SRC_EXTERNAL, otherwise this field will be ignored Please make sure the frequency inputted is equal or greater than BCLK, i.e. sample_rate_hz * slot_bits * slot_num

mclk_multiple: i2s_mclk_multiple_t

< The multiple of MCLK to the sample rate, only take effect for master role

bclk_div: u32

< The division from MCLK to BCLK, only take effect for slave role, it shouldn’t be smaller than 8. Increase this field when data sent by slave lag behind
