If those are the pins that work with the MTS400, once you've found the right definitions thereof, they should work with your board. The schematic you ref'd wasn't there for me so I can't check.
It's looking a bit like this is an I2C interface, in which case I'd closely check the impl code. The I2C for the iris is implemented in software on a fairly advisory level, e.g. it doesn't deal with wait states. I haven't used it anywhere else.
