31:0 DATAP 0x00000000 R Scan Conversion Result Data Peek
The register holds the results from the last scan conversion. Reading this field will not clear SCANDV in ADCn_STATUS or single
DMA request.

30:24 SCANGAIN 0x3F RW Scan Mode Gain Calibration Value
This register contains the gain calibration value used with scan conversions. This field is set to the production gain calibration value
for the 1V25 internal reference during reset, hence the reset value might differ from device to device. The field is unsigned. Higher
values lead to higher ADC results.
23 Reserved
To ensure compatibility with future devices, always write bits to 0. More information in Section 2.1 (p. 3)
22:16 SCANOFFSET 0x00 RW Scan Mode Offset Calibration Value
This register contains the offset calibration value used with scan conversions. This field is set to the production offset calibration
value for the 1V25 internal reference during reset, hence the reset value might differ from device to device. The field is encoded as
a signed 2's complement number. Higher values lead to lower ADC results.
15 Reserved
To ensure compatibility with future devices, always write bits to 0. More information in Section 2.1 (p. 3)
14:8 SINGLEGAIN 0x3F RW Single Mode Gain Calibration Value
This register contains the gain calibration value used with single conversions. This field is set to the production gain calibration value
for the 1V25 internal reference during reset, hence the reset value might differ from device to device. The field is unsigned. Higher
values lead to higher ADC results.
