I am using a PIC16C74. I was wondering if the watchdog timer is automatically reset after the PIC comes out of sleep mode, where the awakaning was caused but a PORTB,0 rising edge interrupt? This could mean that the WDT would reset the chip, if the WDT was just ready to trip when coming out of sleep, and you didn't yet run the CLRWDT in your interrupt service routine code. I would appreciate any information. Thanks! ______________________________________________________ Get Your Private, Free Email at http://www.hotmail.com
