For example,One stream use FIFO and the other stream does not.

What does FIFO behave like when two streams are started at the same time?

The streams are completely independent in this regard.

Talking about FIFO "flushing" makes sense only in P->M case. It gets "flushed" to memory either when it reaches the set threshold, or when the stream is disabled.
