Here, we have a classic example of a PIC being reset by its watchdog timer.
The PIC used in the simulation – 16F866 – has a default watchdog countdown timer of about 2.3 seconds.
So, the count from 0 to 9 is interrupted before the end of the sequence and the program is restarted.
In the following article, we will see how to configure and use a watchdog on a PIC micro-controller.

6 months ago, I have added to my data center a new HP DL380 G7 server.
A superb machine with 2x 6 cores CPU which gives 24 virtual cores, 32GB of DDR3 RAM and 6x SAS 10k 300gb disk .
Soon, I will move the Asterisk and pfSense vmware machines to this server, in addition to some experimental virtual machines : Windows 10, centos and OpenStack.
