  <a name="1206002"> </a><font size=2  face="Verdana, Arial, Helvetica, sans-serif">An interrupt can be raised at a particular instruction count by using the <font size=2 face=Courier><strong>RPC</strong></font> event type in the event file (currently the only event type supported is <font size=2 face=Courier><strong>RPC</strong></font>). If the <font size=2 face=Courier><strong><em>instruction_point</em></strong></font> parameter is zero, the instruction is interrupted. If it is less than zero, the instruction is interrupted and is traced before and after the interrupt handler. This may be used to model aborted instructions. The last parameter is used to specify the interrupt level (0<font  face="Verdana, Arial, Helvetica, sans-serif"> to </font>7 for the ST20) or the address of the interrupt handler, expressed in hexadecimal.</font>
