+<b>Description:</b> The <code>wd_create()</code> function will create a timer by allocating the appropriate resources for the watchdog.

+<code>wd_static()</code> performs the equivalent initialization of a statically allocated <code>struct wdog_s</code> instance.  No allocation is performed in this case.  The initializer definition, <code>WDOG_INITIALIZER</code> is also available for initialization of static instances of <code>struct wdog_s</code>.  NOTE: <code>wd_static()</code> is also implemented as a macro definition.
