你好。

我看I2S規範由sck,ws,sd所組成，但是fx3卻有4組訊號I2S_CLK,I2S_SD,I2S_WS,I2S_MSCLK。

請問有什麼不同?該如何使用?

可以看一下Wikipedia中關於I2S的描述：

The bus consists of at least three lines:

1. Bit clock line
2. Word clock line
3. At least one multiplexed data line

It may also include the following lines:

1. Master clock (typically 256 x LRCLK
2. A multiplexed data line for upload
