Although the controller has encountered a 
problem, the watchdog alarm output has not 
yet been powered. 
If problem persists, the LED will become lit 
constantly, see case #2. 
The controller performs a warm start. 
If it happens only once, the controller 
has performed a restart 
If, however, it happens multiple times, 
then there is an application or hardware 
problem (see case #2)
