I need to understand the PDCA pretty well. Is there a document similar to this one, but for the UC3? http://www.atmel.com/Images/Atme...
In my application it looks like I'll fill a buffer with N+-1 bytes (some times N+1, other times N-1) and then have the PDCA output the data over I2S. Everything works today today except the +-1 functionality which I haven't started on. I'll give it a go when I understand the PDCA really well.
