+//| """Watchdog Timer
+//|
+//| The `watchdog` module provides support for a Watchdog Timer. This timer will reset the device
+//| if it hasn't been fed after a specified amount of time. This is useful to ensure the board
+//| has not crashed or locked up. Note that on some platforms the watchdog timer cannot be disabled
+//| once it has been enabled.
+//|
+//| The `WatchDogTimer` is used to restart the system when the application crashes and ends
+//| up into a non recoverable state. Once started it cannot be stopped or
+//| reconfigured in any way. After enabling, the application must "feed" the
+//| watchdog periodically to prevent it from expiring and resetting the system.
+//|
+//| Example usage::
+//|
+//|     from microcontroller import watchdog as w
+//|     from watchdog import WatchDogMode
+//|     w.timeout=2.5 # Set a timeout of 2.5 seconds
+//|     w.mode = WatchDogMode.RAISE
+//|     w.feed()"""
