一个样品了AVcc A0参照。

/ /软件集ADC10SC开始样品和转换——ADC12SC

/ /自动清除在始新世。ADC12内部振荡器次样品(16 x)

/ /和转换。在等待LPM0中的Mainloop调用MSP430的拯救力量直到ADC12

/ /转换完成,ADC12_ISR将迫使退出LPM0中的Mainloop调用上的

/ / reti。如果A0 > 0.5 * AVcc,p3 4集,否则复位。-A single sample is made on A0 with reference to AVcc.

//　Software sets ADC10SC to start sample and conversion- ADC12SC

//　automatically cleared at EOC. ADC12 internal oscillator times sample (16x)

//　and conversion. In Mainloop MSP430 waits in LPM0 to save power until ADC12

//　conversion complete, ADC12_ISR will force exit from LPM0 in Mainloop on

//　reti. If A0 > 0.5*AVcc, P3.4 set, else reset.
