I have been looking at the rx port. Seems to be very similar to mine in 
that it has an add and adc where both set the flags and no explicit hard 
register for cc. Mine is actually simpler in that there is only CCmode 
since we don't have floating point operations in the chip. Will use rx 
as a guide! :)
