| 9:0 | OFFCAL | R/W | 0h | ADC Post Processing Block 2 Offset Correction. This bit field can be used to digitally remove any system level offset inherent in the ADCIN circuit. This 10-bit signed value is subtracted from the ADC output before being stored in the ADCRESULT register. 000h No change. The ADC output is stored directly into ADCRESULT. 001h ADC output - 1 is stored into ADCRESULT. 002h ADC output - 2 is stored into ADCRESULT. ... 200h ADC output + 512 is stored into ADCRESULT. ... 3FFh ADC output + 1 is stored into ADCRESULT. NOTE: In 16-bit mode, the subtraction will saturate at 0000hand FFFFh before being stored into the ADCRESULT register. In 12-bit mode, the subtraction will saturate at 0000hand 0FFFh before being stored into the ADCRESULT register. Note: in the case that multiple PPBs point to the same SOC, only the OFFCAL of the lowest numbered PPB will be applied. |
