AM2634-Q1: SW driver for changing adcX_cfg_1p1v register to configure the "ADC Output Code Clip and Shift Options"

Part Number: AM2634-Q1

Hi BU experts, 

In TRM, there are 4 options for ADC output code: 

And it's said that the program can change the adcX_cfg_1p1v register by following steps: 

I can find the above registers' declaration in SDK: 

But from application perspective, we don't have this register description so we can't write codes to manipulate it. And also there are no related APIs in SDK. 

We want to change adcX_cfg_1p1v[79:80] to b'10.  How can we do this? 

BR,
