NAME
SE[3:0]
DESCRIPTION
Unused.
Single-ended signal source multiplexer. SE[3] = MSB.
Unused.

CNVT1
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
CNVT2
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.
0
CNVTT
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.
