TMS320F28379D: TMS320F28379D ADC Calibration code?

Hi Team,

In F28379D example project, we found below code for adc trim. The method is quite different compared to F28335 adc_cal (function).

Could you help advise if we have any documents for below code? Thanks.

            // ******************************************************

            // static analog trim for all ADCs (A, B, C and D)

            // *******************************************************

            adc_cal=(int*)0x0000743F;

            *adc_cal=0x7000;

            adc_cal=(int*)0x000074BF;

            *adc_cal=0x7000;

            adc_cal=(int*)0x0000753F;

            *adc_cal=0x7000;

            adc_cal=(int*)0x000075BF;

            *adc_cal=0x7000;
