尊敬的TI工程师，你们好，就是我想配置控制进入10位AD的中断时间，根据data sheet上的配置，但是没有什么效果，总是以30us进入中断，请问如何配置解决？
ADC10CTL0 |= ADC10SHT_6 + ADC10ON+ADC10MSC; // ADC10ON, S&H=16 ADC clks
ADC10CTL1 |= ADC10SHP+ADC10CONSEQ_2; // ADCCLK = MODOSC; sampling timer
ADC10CTL2 |= ADC10RES+ ADC10DF; // 10-bit conv result; signed format
ADC10MCTL0 |= ADC10INCH_3; // A1 ADC input select; Vref=AVCC
ADC10IE |= ADC10IE0; // Enable ADC conv complete interrupt
ADC10CTL0 |= ADC10ENC ; // Sampling and conversion start
