In 8-input mode, two neighboring ADCs are used to convert a single input. The register map relative to the ADCs can be mapped to the eight channels, as shown in Table 42.
REGISTER MAP NOTATION | MAPPING TO CHANNELS IN 16-INPUT MODE | EXAMPLE |
---|---|---|
GAIN_ADCxo,
GAIN_ADCxe of two adjacent channels |
GAIN_CHANNELx | GAIN_CHANNEL1 = GAIN_ADC1o (same for GAIN_ADC1e, GAIN_ADC2o, and GAIN_ADC2e)
Set odd and even gains of two adjacent ADCs to the same setting. |
OFFSET_ADCxo,
OFFSET_ADCxe |
OFFSET_CHANNELx | OFFSET_CHANNEL1 = OFFSET_ADC1o (same for OFFSET_ADC1e, OFFSET_ADC2o, and OFFSET_ADC2e)
Set odd and even offsets of two adjacent ADCs to the same setting. |
PDN_DIG_ADCx of two adjacent channels | PDN_DIG_CHANNELx | PDN_DIG_CHANNEL1 = PDN_DIG_ADC1 (same for PDN_DIG_ADC2)
Set the power-down for two adjacent ADCs to the same setting. |
PDN_ANA_ADCx of two adjacent channels | PDN_ANA_CHANNELx | PDN_ANA_CHANNEL1 = PDN_ANA_ADC1 (same for PDN_ANA_ADC2)
Set the power-down for two adjacent ADCs to the same setting. |
DIG_HPF_EN_ADCx | Mapped to 2 channels | DIG_HPF_EN_CHANNEL1-2 = DIG_HPF_EN_ADC1-4
Common setting for 4 ADCs mapped to the common setting for 2 channels. |
HPF_CORNER_ADCx | Mapped to 2 channels | HPF_CORNER_CHANNEL1-2 = HPF_CORNER_ADC1-4
Common setting for 4 ADCs mapped to the common setting for 2 channels. |
