there is a processor, mh6211 for the early ones, h8 500 for the evo 5 and 6,mh 720 for 7 and 8's, not sure about the 9's presume its the same seen it flashes the same as 7's and 8's
the early stuff uses the processor for the input/output signals and uses the eprom for stored address's(answers) as to output a signal to the various sensors through the pinouts |
is it a hard wired program into the processor? or does it load it from another rom?
