All of Port E (and most of A-G, except what is used on-board)
is brought out on the 51 pin connector on mica devices.
Presumably the IRIS uses the same layout. Here's my cheat:

Great that you know the timers! It sure would be nice to have
TOS support for more of the micro-controller features. And to
know which are already being used (I had to reverse engineer
which Timers were used in T1...) I already ref'd my humble
attempts at PWM and Capture in this thread if it's of any
use to you, see under Motes above...
