// @Function      void WDT_vInit(void) 
//
//----------------------------------------------------------------------------
// @Description   This is the initialization function of the 'Watch Dog 
//                Timer' function library. It is assumed that the SFRs used 
//                by this library are in their reset state. 
//                
//                The watchdog timer is used.
//                The following SFR fields will be initialized:
//                WDTREL - WDT reload value
//                WDTIN  - WDT input frequency selection
//                Then the watchdog timer will be refreshed.
//                Note: The user has to take care that RMAP bit in SYSCON0 is 
//                to be set while using the registers of Watch dog timer.
//                Registers are WDTCON,WDTWINB,WDTREL,WDTH,WDTL
