Chapter 6 Setup
6.15 Watch Dog
IMC SDK provides a simple WatchDog function. When watchdog is enabled, if the
user doesn’t trigger the counting within the timing you set, watchdog will force to boot
up. This function can prevent TREK-668 from hanging up in unexpected condition.
User needs to set a time, and enable the sensor in the program during the time you
set to prevent the system hang up in special condition.
