28377ad采样差分模式怎么配置

Other Parts Discussed in Thread: C2000WARE

我用的是LAUNCHPad 的F28377S官方的开发板

我想把AD配置成差分模式,但是没有在CONTROLCUITE中找到例程,我配置了以下语句

AdcSetMode(ADC_ADCA, ADC_RESOLUTION_12BIT, ADC_SIGNALMODE_DIFFERENTIAL);

AdcaRegs.ADCSOC0CTL.bit.CHSEL=0;

这样配置是不是用ADCINA0和ADCINA1两个pin口作为正负极的输入端,采样得到的值存放在哪个寄存器里啊?
