CC2640R2L: Use ADC on CC2640R2L

Hi,

I just got little confused about ADC between CC2640R2L and CC2640R2F.

In TRM chapter 17, looks like this is for CC2640R2F sensor controller only..

For CC2640R2L, I only know there are 2 ADC examples inside SDK/driver folder.

So I have 2 questions:

1. What's the difference of ADC between CC2640R2L/F?? I know sensor controller can let system save more power.

2. Regard to CC2640R2L, i only know ADC.h and 2 ADC examples inside SDK, is there any way to change ADC setting like V reference / gain / offset / calibration ..etc??

Thanks very much for e2e support.
