XDATA&lt;br /&gt;
&lt;br /&gt;
&lt;i&gt;If I use the Large memory model, do I have to define vars as xdata myvar? How does this affect using on-chip xram and real external ram?&lt;/i&gt;&lt;br /&gt;
&lt;br /&gt;
If you drive a steamroller do you have to yeld? - same question.&lt;br /&gt;
&lt;br /&gt;
When using the large memory model you have to select what must be fast - that is an order of maginitude more difficult than selecting what can be slow (typically arrays).&lt;br /&gt;
