MSP430的ADC12,采用单通道多次采样的模式,未开中断,请问:第一,ad转换完成后,如果上次转换结果未读取,本次转换结果是否覆盖原有数据?第二,结果是否存放在ADC12MEM0?

MSP430的ADC12,采用单通道多次采样的模式,未开中断,请问:第一,ad转换完成后,如果上次转换结果未读取,本次转换结果是否覆盖原有数据?第二,结果是否存放在ADC12MEM0?
谢谢,请问下面代码有问题吗
通道7
P6SEL |= 0x80; // ADC sampled on P6.7
ADC12CTL0 &= ~ENC; //ADC12CTL0 page807
ADC12CTL0 &= ~(REFON | ADC12SC);
ADC12CTL0 = ADC12ON|SHT0_2; // turn on ADC12
// Sample and hold for 16 ADC12CLK cycles
ADC12CTL1 &= ~ISSH;
ADC12CTL1 |= (SHP | CONSEQ_2 | ADC12SSEL0 | ADC12DIV_0 | SHS_0 | CSTARTADD_0); //单通道多次采样 // Use sampling timer
ADC12MCTL0 |= (SREF_5 | INCH_7); // Vr+=VREF+ (external) & Vr- = VREF-;Channel 7
ADC12CTL0 |= ENC; // Enable conversions
ADC12CTL0 |= ADC12SC; // Start conversions
