Yes, and also they may have different current limits in EPP mode. In general P-port pins can sink more current than they can source (generally 15mA, plenty to light an LED) so low-side switching works better. -- atp "A motorcycle is a bicycle with a pandemonium attachment and is designed for the especial use of mechanical geniuses, daredevils and lunatics." — George Fitch, Atlanta Constitution Newspaper, 1912 _______________________________________________ Emc-users mailing list Emc-users@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/emc-users
