|
<p><a name="index-Z8000-support-2693"></a>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>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.
