//******************************************************************************
// MSP430F20x2 Demo - ADC10, Sample A1, AVcc Ref, Set P1.0 if > 0.5*AVcc
//
// Description: A single sample is made on A1 with reference to AVcc.
// Software sets ADC10SC to start sample and conversion - ADC10SC
// automatically cleared at EOC. ADC10 internal oscillator times sample (16x)
// and conversion. In Mainloop MSP430 waits in LPM0 to save power until ADC10
// conversion complete, ADC10_ISR will force exit from LPM0 in Mainloop on
// reti. If A1 > 0.5*AVcc, P1.0 set, else reset.
