Are you really sure you want to do that ?
Your peripheral really require such I2C bandwidth that you just can't
use the actual code ?

Well, my last attempt was just to use interrupt to know when a
transfer was done instead of busy waiting. And I never got any
interrupts for the second I2C controller ( the one wired on the
lite5200 board ) unless I init both I2C controllers. I haven't yet
figured why ...

To get back at your original question, IIRC the BestCommAPI
package(Some big zip freescale will send you if you ask several times
;) ) has some code example of all devices, somewhere in a "validation"
directory. I can't send it, it's (c) Freescale.
