Hmmm....the flash and the CPU are opposite each other? Interesting. I wonder if that was done on purpose to make it harder to mess with things, or they just ended up that way because it made the layout and routing simpler?<p>If they were not opposite each other, then the following approaches to spying on or tampering with the system would be possible:<p>• Cut the write signal between the CPU and the flash so that the CPU cannot erase anything in the flash.<p>• Cut all the control, data, and address lines between the CPU and the flash and insert a man-in-the-middle device that can allow or block CPU access to the flash and that can read&#x2F;write the flash itself.
