 + ​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.
