+//! <h1>Watchdog (watchdog)</h1>

+//!

+//! This example application demonstrates the use of the watchdog as a simple

+//! heartbeat for the system.  If a watchdog is not periodically fed, it will

+//! reset the system.  The GREEN LED will blink once every second to show

+//! every time watchdog 0 is being fed, the Amber LED will blink once every

+//! second to indicate watchdog 1 is being fed. To stop the watchdog being fed

+//! and, hence, cause a system reset, tap the left screen to starve the

+//! watchdog 0, and right screen to starve the watchdog 1.

+//!

+//! The counters on the screen show the number of interrupts that each watchdog

+//! served; the count wraps at 255.  Since the two watchdogs run in different

+//! clock domains, the counters will get out of sync over time.
