Memory Configuration A
When the device is set in ATmega161 compatibility mode, the internal address space is 1,120
bytes. This implies that the first 1,120 bytes of the external memory can be accessed at
addresses 0x8000 to 0x845F. To the Application software, the external 32 KB memory will
appear as one linear 32 KB address space from 0x0460 to 0x845F.
