Hey Doug, I meant clearing the flags after setting EXTMODE as suggested on pg.68. EXTMODE = 0x08; //only controls the sensitivity EXTINT = 0x08; //clear EINT3 flag ... ... VICIntEnable = (1<<VIC_EINT3); // Enable external 3 interrupt. Your 2nd reply (which just came) looks kinda spooky. What kind-off exception r u getting? If EINT0-2 can work on edge sensitive mode, then I wouldn't give up on EINT3 quite yet. There's must be a way to get around to it. Good luck, Leighton __________________________________ Do you Yahoo!? New and Improved Yahoo! Mail - Send 10MB messages! http://promotions.yahoo.com/new_mail
