Introduction - If you have any usage issues, please Google them yourself
A single sample is made on A10 with reference to internal
1.5V Vref. Software sets ADC12SC to start sample and conversion - ADC12SC
automatically cleared at EOC. ADC12 internal oscillator times sample
and conversion. In Mainloop MSP430 waits in LPM0 to save power until
ADC10 conversion complete, ADC12_ISR will force exit any LPMx in
Mainloop on reti.
