//----------------------------------------------------------------------------
// @Description   This is the initialization function of the ADC function 
//                library. It is assumed that the SFRs used by this library 
//                are in their reset state. 
//                
//                Following SFR fields will be initialized:
//                GLOBCTR  - Global Control
//                PRAR     - Priority and Arbitration Register
//                ETRCR    - External Trigger Control Register
//                CHCTRx   - Channel Control Register x
//                RCRx     - Result Control Register x
//
//----------------------------------------------------------------------------
// @Returnvalue   None
