When the device is set in ATmega103 compatibility mode, the internal address space is
4,096 bytes. This implies that the first 4,096 bytes of the external memory can be
accessed at addresses 0x8000 to 0x8FFF. To the Application software, the external 32
KB memory will appear as one linear 32 KB address space from 0x1000 to 0x8FFF.
