When the Kinetis K10 receives a stereo audio data stream, i get each audio sample reading the receiver FIFO (using DMA). How can i know which audio sample was first in frame and which one was second in frame? Do they always load as pairs? I mean there should be a proven and reliable method to resolve this. Something similar happens with the transmitter: When i stream data into the transmitter FIFO, how can i know when to put the first word of a frame?
