Looking at the digital pins labeled on the board, which is port0 and which is port 1. The digital pin header is a double header so how is this labeled? A,B? 0,1?
Not sure I quite understand your question, but maybe the port labeling on the mbed site for this board will help you?

The board user manual is available here:
I just noticed the schematic for the board seems to have been taken down so we'll get that posted again. I've attached it here for convenience.
This is just what I was looking for. Thank you.
