**     Filename  : WDog1.C
**     Project   : Flash
**     Processor : MC9S08JM60CLHE
**     Component : WatchDog
**     Version   : Component 02.121, Driver 01.14, CPU db: 3.00.046
**     Compiler  : CodeWarrior HCS08 C Compiler
**     Date/Time : 2010-1-12, 18:20
**     Abstract  :
**         This device "WatchDog" implements a watchdog.
**         When enabled, the watchdog timer counts until it reaches
**         a critical value corresponding to the period specified
**         in 'Properties'. Then, the watchdog causes a CPU reset.
**         Applications may clear the timer before it reaches the critical
**         value. The timer then restarts the watchdog counter.
**         Watchdog is used for increasing the safety of the system
**         (unforeseeable situations can cause system crash or an
**         infinite loop - watchdog can restart the system or handle
**         the situation).
**
**         Note: Watchdog can be enabled or disabled in the initialization
**               code only. If the watchdog is once enabled user have
**               to call Clear method in defined time intervals.
**     Settings  :
**         Watchdog causes             : Reset CPU

**         Clock Source                : Internal clock 1-kHz

** ===================================================================
**     Method      :  WDog1_Clear (component WatchDog)
**
**     Description :
**         Clears the watchdog timer (it makes the timer restart from
**         zero).
**     Parameters  : None
**     Returns     :
**         ---             - Error code, possible codes:
**                           ERR_OK - OK
**                           ERR_SPEED - This device does not work in
**                           the active speed mode
**                           ERR_DISABLED - The Bean is disabled
