我用官网给出的12bit单端信号采用的ADC例程改成16bit差分输入的时候没有成功。我把
AdcaRegs.ADCCTL2.bit.SIGNALMODE = 1; // single-ended channel conversions (12-bit mode only)
AdcaRegs.ADCCTL2.bit.RESOLUTION = 1; // 12-bit resolution
改成这样,但是采样的结果还是12bit的,请问这是什么原因?

请TI的技术支持回复一下这个问题。用的样片型号是XF28377DPTP YF A-3BATZSW,版本号是A,AD采样的问题(具体见上面)是不是跟芯片的版本号有关?
