+ CAUTION: This property should be used with care, it actually makes the
+ watchdog not counting when the CPU is in idle state, therefore the
+ watchdog reset time depends on mean CPU usage and will not reset at all
+ if the CPU stop working while it is in idle state, which is probably
+ not what you want.
