hantto said:Hi, would this kind of reset circuitry work?
By taking RE0 low it would trigger the 555 and give a 1second pulse to Q5 wich in turn pulls MCLR to GND.
hantto said:I have always found the WDT to be a strange thing and have not completely understood what it is for. And the datasheet doesn't give much information about it (under a page). Where could I find aditional information about the WDT?

hantto said:One question tough, if the WDT resets the PIC, does it have EXACTLY the same effect as externaly reseting the PIC would have?
Exo said:why do you need the 555? You can use RE0 to pull MCLR down directly...
If you need a 1second delay or something just do that in software...

You can't do a 1 second delay in software, as soon as MCLR goes LOW the PIC stops running, then as it goes high again it starts running from a full hardware reset.
