Expand description
@brief Reconfigure the I2S clock for TDM mode
@note Only allowed to be called when the channel state is READY, i.e., channel has been initialized, but not started
this function won’t change the state. i2s_channel_disable
should be called before calling this function if I2S has started.
@note The input channel handle has to be initialized to TDM mode, i.e., i2s_channel_init_tdm_mode
has been called before reconfiguring
@param[in] handle I2S channel handler
@param[in] clk_cfg Standard mode clock configuration, can be generated by I2S_TDM_CLK_DEFAULT_CONFIG
@return
- ESP_OK Set clock successfully
- ESP_ERR_INVALID_ARG NULL pointer, invalid configuration or not TDM mode
- ESP_ERR_INVALID_STATE This channel is not initialized or not stopped
