1 = Initiate conversion on channel 1 using ADC settings specified in registers ADC_Config_1A and
ADC_Config_1B. The ADC result is stored in ADC_Data_1. CPU is halted during the conversion
process. This bit is automatically reset to zero when conversion is completed.
1 = Initiate conversion on channel 2 using ADC settings specified in registers ADC_Config_2A and
ADC_Config_2B. The ADC result is stored in ADC_Data_2. CPU is halted during the conversion
process. This bit is automatically reset to zero when conversion is completed.
1 = Initiate conversion on temperature sensor using ADC settings specified in registers
ADC_Config_TA and ADC_Config_TB. The ADC result is stored in ADC_Data_T. CPU is halted during
the conversion process. The bit is automatically reset to zero when conversion is completed.

No measurement.
Convert the temperature sensor signal using the settings in
ADC_Config_TA and ADC_CONFIG_TB, storing the result in the
ADC_Data_T register.
Convert the differential signal INP2-INM2 using the settings in
ADC_Config_2A and ADC_Config_2B, storing the result in the ADC_Data_2
register.
Convert the differential signal INP1-INM1 using the settings in
ADC_Config_1A and ADC_Config_1B, storing the result in the ADC_Data_1
register.
Not used for any setting of SE[3:0] ≠ 0000.
Convert the single-sided signal indicated by SE[3:0] using the settings in
ADC_Config_2A and ADC_Config_2B, if appropriate, storing the result in
the ADC_Data_2 register.
Convert the single-sided signal indicated by SE[3:0] using the settings in
ADC_Config_1A and ADC_Config_1B, if appropriate, storing the result in
the ADC_Data_1 register.
