/** 
 * This component allows a client to access the MSP430 ADC12
 * (12-bit analog-to-digital converter) via the <code>ReadStream</code>
 * interface. A client must wire the <code>Msp430Adc12Config</code> interface
 * to a component that returns its ADC12 configuration data. Depending on the
 * REF_VOLT_AUTO_CONFIGURE switch (defined in Msp430Adc12.h) the internal
 * reference voltage generator is automatically enabled if and only if the
 * configuration data includes VREF as reference voltage.
 *
 * @author Jan Hauer
 * @see  Please refer to TEP 101 for more information about this component and its
 *          intended use.
