Vitaly, When I get a little free time I'll go back and look through the Programmer's Reference document and driver source code to see if I can find out for sure. It's been quite a while since I looked at them. We ultimately got three or four additional documents beyond the "basic specs" they make public. The answer should be there somewhere, I think. It will also be interesting to see if Microchip decides to make these modules "Microchip-centric" or not as they really do have a broad appeal beyond bolting them up to PICs.
