// @Function      void ASC_vInit(void)

//----------------------------------------------------------------------------
// @Description   This function initializes the ASC component. It effects all
//                necessary configurations of the SFR, depending on the selected
//                operating mode. The configuration determines whether the ASC
//                interrupts are to be released, and the priority of the 
//                released interrupt.
//
//----------------------------------------------------------------------------
// @Returnvalue   none
