 Data Transport
 ^^^^^^^^^^^^^^
 
-The data transport of I2S peripheral, including sending and receiving, is realized by DMA. Before transporting data, please call :cpp:func:`i2s_channel_enable` to enable the specific channel. When the sent or received data reach the size of one DMA buffer, ``I2S_OUT_EOF`` or ``I2S_IN_SUC_EOF`` interrupt will be triggered. Note that the DMA buffer size is not equal to :cpp:member:`i2s_chan_config_t::dma_frame_num`, one frame here means all the sampled data in one WS circle. Therefore, ``dma_buffer_size = dma_frame_num * slot_num * slot_bit_width / 8``. For the transmit case, users can input the data by calling :cpp:func:`i2s_channel_write`. This function will help users to copy the data from the source buffer to the DMA tx buffer and wait for the transmition finished. Then it'll repeat until the sent bytes reach the given size. For the receive case, the function :cpp:func:`i2s_channel_read` will wait for receiving the message queue which contains the DMA buffer address, it will help users to copy the data from DMA rx buffer to the destination buffer.

 Both :cpp:func:`i2s_channel_write` and :cpp:func:`i2s_channel_read` are blocking functions, they will keep waiting until the whole source buffer are sent or the whole destination buffer loaded, unless they exceed the max blocking time, then the error code `ESP_ERR_TIMEOUT` will return in this case. To send or receive data asynchronously, callbacks can be registered by  :cpp:func:`i2s_channel_register_event_callback`, users are able to access the DMA buffer directly in the callback function instead of transmitting or receiving by the two blocking functions. However, please be aware that it is an interrupt callback, don't do complex logic, floating operation or call non-reentrant functions in the callback.
