AKR è l'equivalente del program_counter dei microprocessori casalinghi, 
ha 16bit (ed indirizza 128kb con 2 banchi da 64, vedi pag.2-1) infatti 
non indirizza in modo lineare oltre $FFFF ed il resto lo vede su switch 
separati che separano i banchi di memoria per un'indirizzamento lineare.

IAR è l'equivalente dell'accumulatore, ed ha 4 accumulatori, tutti da 
16bit: ok adesso sappiamo per davvero che è un computer a 16bit e non ad 
8 bit.
