So, you think interrupt and management overhead of the software to send a
couple of bytes on a 100k serial interface is free?  The chip designers are
often upset when you don't use every feature, but you need to apply some
real systems engineering methods and analyze how all of these little things
help (or hurt) your application.
Most important reason for me to do the i2c with the RISC is the scalebility:
if the application needs to do a lot more i2c io as expected it won't affect
the overal performance.
