/** 
 * This component realizes the HAL1 representation and allows an
 * MSP430-specific client to access the MSP430 ADC12 (12-bit analog-to-digital
 * converter) via the <code>Msp430Adc12SingleChannel</code> and
 * <code>Resource</code> interface.  According to TEP 108 a client must reserve
 * the ADC before using it via the <code>Resource</code> interface (otherwise
 * the request will fail). In contrast to the <code>Msp430Adc12ClientC</code>
 * the <code>Msp430Adc12RefVoltAutoClientC</code> automatically enables the
 * internal reference voltage generator if and only if the configuration data
 * defined via the <code>Msp430Adc12Config</code> interface includes VREF as
 * reference voltage. I.e. the <code>Resource.granted()</code> event implies
 * that the reference voltage is stable. 
 * 
 * @author Jan Hauer
 * @see  Please refer to TEP 101 for more information about this component and its
 *          intended use.
