Hello all!
I just wanted to try and understand something with EOMA-68 -- just a small question that's not explained well on the Wiki page. I had a design idea that I wanted to draw up (not much of the actual circuitry -- I'm not that good -- but enough so that some electronics engineers can "fill in the blanks", if you will, with the circuitry I can't figure out), but I've got to get this figured out first.
So I can sort of figure out that external to the CPU Card, there needs to be an I2C EEPROM. What I can't quite figure out is the purpose of that EEPROM. I'm *guessing* that it's for IDing what the external interfaces are on the host board / carrier board (the PCB that the CPU Card plugs into) so that the CPU card can turn off what's not needed, and provide proper I/O protocols to what is needed -- but that's only a guess, because it's extremely unclear on the Wiki page.
Would you folks be able to provide some clarification?
Thanks!
Christopher
