Hello Community,

Does the SAI sub-block clock source matter when it is in Synchronous Slave mode with the other sub-block? In other words, should the two sub-blocks have the same clock source?

Thank you.

Hello,

To use two block SAI working synchronously, you need to configure the first block as an asynchronous master and the other one as a synchronous slave. Then, The two blocks will share the FS ,BCLK and MCLK lines. And each one will have its own data line.
