Haven't been able to get through to Mchip, so I'll ask here. Running the F627, when I execute the sleep instruction, the ice breaks with a stack underflow. Is this normal? Is there anything I can do about this? -- Dave's Engineering Page: http://www.dvanhorn.org Where's dave? http://www.findu.com/cgi-bin/find.cgi?kc6ete-9 -- http://www.piclist.com hint: The PICList is archived three different ways.
