| <p>The Z8000 as supports both members of the Z8000 family: the |
| unsegmented Z8002, with 16 bit addresses, and the segmented Z8001 with |
| 24 bit addresses. |
| </p> |
| <p>When the assembler is in unsegmented mode (specified with the |
| <code>unsegm</code> directive), an address takes up one word (16 bit) |
| sized register. When the assembler is in segmented mode (specified with |
| the <code>segm</code> directive), a 24-bit address takes up a long (32 bit) |
| register. See <a href="Z8000-Directives.html#Z8000-Directives">Assembler Directives for the Z8000</a>, |
| for a list of other Z8000 specific assembler directives. |
