Ok .... thanks guys I understand better (I guess
But... (whatever is did all is hardware at the end, whatever I press on the pad all is "hardware" translated after).
Whatever was happened before (a software code sent to the CPU or any chip, or anything else soft or hard), when the console resest, inevitably the reset itself is hardware, that's inevitably due to a "hardware fonction" somewhere in the console (surely near or in the supply input), and this is surely due to a "signal" sent by a hardware component to another hardware component who control the "reset event".
This is what I want to know.
Else how to know how all of this work?
(Hope my english is good enough)
Thanks again guys
