The only specific requirement is that it uses RETI to return (not
RET).&lt;/p&gt;

&lt;p&gt;
See also chapter 2 of the so-called &amp;quot;bible&amp;quot; for the 8051:&lt;/p&gt;

&lt;p&gt;
Chapter 2 - 80C51 Family Programmer&amp;#39;s Guide and Instruction
Set:&lt;br /&gt;

&lt;p&gt;
The 8051 interrupt structure is described in Chapters 1 and 3:&lt;/p&gt;
