/** 
 * This component is meant to intercept requests to the <code>Resource</code>
 * interface on their way to the adc arbiter. It checks whether the client's
 * adc configuration requires the internal reference voltage generator of the
 * MSP430 to be enabled during the conversion by inspecting the client's
 * configuration data (using the <code>AdcConfigure</code> interface). If so it
 * makes sure that Resource.granted() is held back until the reference voltage
 * is stable. Clients SHOULD NOT wire to <code>Msp430RefVoltArbiterP</code> but
 * to the Resource interface provided by
 * <code>Msp430Adc12ClientAutoRVGC</code>.
