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 ..
