Note1: Internal 512KByte File Flash & Expansion Card 1MByte
      File Flash are not memory mapped. They are accessed
      through a serial buss.
Note2: Memory areas that repeat are an artifact that's
      caused by simple hardware design techniques. It
      is not a good idea to rely upon these areas since
      they can disappear in future hardware versions.
