//  MSP430F21x2 Demo - ADC10, DTC Sample A2-0, AVcc, Single Sequence, DCO
//
//  Description: Sample A2/A1/A0 as single sequence with reference to AVcc.
//  Software sets ADC10SC to trigger sample sequence. In Mainloop MSP430 waits
//  in LPM0 to save power until ADC10 conversion complete, ADC10_ISR(DTC) will
//  force exit from any LPMx in Mainloop on reti. ADC10_ISR will force LPM0
//  exit. ADC10 internal oscillator times sample period (16x) and conversion
//  (13x). DTC transfers conversion code to RAM 200h - 206h. P1.0 set at start
//  of conversion burst, reset on completion.

这是官网上的一个示例，我想问下A2，A1，A0口的转换好的数据都放在哪了，该怎样调用转换好的数据呀，ADC10MEM好像只能存放一个数据吧，请各位帮忙指点下吧～～～ 此帖出自小平头技术问答
