i just have a really fast look to this. Try to find something in JAL who can gives you SPI or Microwire protocol read/write. That's all i can tell you for now. BTW i'm begining in a few hours some code line to do some playback/record from this chip.

You can give a try with the free PBP compiler on http://www.compilespot.com/startdemo.htm too.

i agree it's a bit limited, but that way, everybody here will be able to help you for your project.
