+===== Defeating the watchdog timer =====
+To defeat the watchdog, use the **Watchdog()** function or the **watchdog** inline function (one is inlined, one is a function call).
+If that isn't defined in your version of the SDK, use the following code snippit:
+<code>
+#ifdef _ARM_
+    #include "board.h"
+    TMyApplication *const MyApplication = (TMyApplication*) 0x300000;
+    // restart the watchdog
+    inline void Watchdog() {
+        AT91C_BASE_WDTC->WDTC_WDCR= 0xA5000001;
+    }
+    void watchdog();
+// same function as above, but not inlined...
+#else
+    extern TMyApplication MYAPPLICATION;
+    TMyApplication *const MyApplication= &MYAPPLICATION;
+    inline void Watchdog() { }
+#endif
+</code>
+Don't forget to define MYAPPLICATION in the Windows-only part of the code somewhere.
