Configration
| ADCMODE | ADC Mode 0 (NORMAL): High speed mode with a maximum CLK_ADC of 10 MHz. 1 (HIGHSPEED): Double high speed mode with a maximum CLK_ADC of 20 MHz. Power consumption is boosted to allow faster conversions. 2 (HIGHACCURACY): High accuracy mode with maximum CLK_ADC of 5 MHz. |
| OSRHS | High Speed OSR 0 (HISPD2): High speed over sampling of 2x. 1 (HISPD4): High speed over sampling of 4x. 2 (HISPD8): High speed over sampling of 8x. 3 (HISPD16): High speed over sampling of 16x. 4 (HISPD32): HIgh speed over sampling of 32x. 5 (HISPD64): High speed over sampling of 64x. |
| OSRHA | High Accuracy OSR 0 (HIACC16): High accuracy over sampling of 16x. 1 (HIACC32): High accuracy over sampling of 32x. 2 (HIACC64): High accuracy over sampling of 64x. 3 (HIACC92): High accuracy over sampling of 92x. 4 (HIACC128): High accuracy over sampling of 128x. 5 (HIACC256): High accuracy over sampling of 256x. |
| ANALOGGAIN | Analog Gain 1 (ANAGAIN0P5): Analog gain of 0.5x. 2 (ANAGAIN1): Analog gain of 1x. 3 (ANAGAIN2): Analog gain of 2x. 4 (ANAGAIN3): Analog gain of 3x. 5 (ANAGAIN4): Analog gain of 4x. |
| REFSEL | Reference Select 0 (VBGR): Internal 1.21 V reference. 1 (VREF): External Reference. (Calibrated for 1.25V nominal.) 2 (VREF2P5): External Reference. Supports 2.5V in high accuracy mode. 3 (VDDX): AVDD (unbuffered) 4 (VDDX0P8BUF): AVDD (buffered) * 0.8 |
| DIGAVG | Digital Averaging 0 (AVG1): Collect one output word (no digital averaging). 1 (AVG2): Collect and average 2 digital output words. 2 (AVG4): Collect and average 4 digital output words. 3 (AVG8): Collect and average 8 digital output words. 4 (AVG16): Collect and average 16 digital output words. |
| TWOSCOMPL | Two’s Complement 0 (AUTO): Automatic: Single ended measurements are reported as unipolar and differential measurements are reported as bipolar. 1 (FORCEUNIPOLAR): Force all measurements to result in unipolar output. Negative differential numbers will saturate to 0. 2 (FORCEBIPOLAR): Force all measurements to result in bipolar output. Single ended measurements are half the range, but allow for small negative measurements. |
