// @Function void ADC_vConfConv(ubyte ubMode, ubyte ubChannel)
//
//----------------------------------------------------------------------------
// @Description This function configures a new A/D conversion. In fixed
// channel single conversion mode (ADC_FIXED) the forwarded
// channel is converted once. In fixed channel continuous
// conversion mode (ADC_FIXED_CONTI) the forwarded channel is
// converted continuously. In auto scan single conversion mode
// (ADC_SCAN) a sequence beginning with the forwarded channel
// and ending with channel 0 is converted. In auto scan
// continuous conversion mode (ADC_SCAN_CONTI) the sequence is
// converted continuously. To start the conversion it is
// necessary to call ADC_vStartConv().
// Note:
// While a conversion is in progress, the mode and the channel
// may be changed. The new mode will be evaluated after the
// current conversion. The new channel will be evaluated after
// the current conversion (fixed channel modes) or after the
// current conversion sequence (auto scan modes). The
// following constants are available for ubMode:
// ADC_FIXED
// ADC_FIXED_CONTI
// ADC_SCAN
// ADC_SCAN_CONTI
//
// The following constants are available for ubChannel:
// ADC_ANA_0 .. ADC_ANA_7 and
// ADC_ANA_10 .. ADC_ANA_15 (see @Defines in header file)

// @Returnvalue None
