The uer manual tells.&lt;/p&gt;

&lt;p&gt;
It checks if the vector table is valid. If not, it hangs in boot
loader.&lt;br /&gt;
If yes, it checks if code protect. If yes, it jumps to program.&lt;br /&gt;
If not code protect, it checks one IO pin. If active, it stays in
boot loader - else jumps to program.&lt;/p&gt;

&lt;p&gt;
And &amp;quot;jumps to program&amp;quot; means it picks up the value from your
specified reset vector to know where to jump.&lt;/p&gt;
&lt;/p&gt;&lt;div style="clear:both;"&gt;&lt;/div&gt;</description></item></channel></rss>
