Task Watchdog Timer (TWDT)
--------------------------

The Task Watchdog Timer (TWDT) is used to monitor particular tasks, ensuring that they are able to execute within a given timeout period. The TWDT primarily watches the {IDF_TARGET_IDLE_TASKS}, however any task can subscribe to be watched by the TWDT. By watching the {IDF_TARGET_IDLE_TASKS}, the TWDT can detect instances of tasks running for a prolonged period of time wihtout yielding. This can be an indicator of poorly written code that spinloops on a peripheral, or a task that is stuck in an infinite loop.
