Ditto on this!

The overhead & cost of the Max31xx family was overtaken by the advantages of 
using another AVR. It was cheaper, could be put to sleep, could offload packet 
processing etc.  More importantly it could do anything that we dreampt up at a 
later date.  By using it as a comms processor it kept a lot of byte interrupts 
away from the main processor and only sent valid packet interrupts, a bit the 
way that CAN does.
