DAEN—DMA_ADC Enable  
0 = DMA_ADC is disabled and the ADC Analog Input Number (ADC_IN) is reset to 0.  
1 = DMA_ADC is enabled.  
IRQEN—Interrupt Enable  
0 = DMA_ADC does not generate any interrupts.  
1 = DMA_ADC generates an interrupt after transferring data from the last ADC Analog  
Input specified by the ADC_IN field.  
Reserved  
These bits are reserved and must be 0.  
ADC_IN—ADC Analog Input Number  
These bits set the number of ADC Analog Inputs to be used in the continuous update (data  
conversion followed by DMA data transfer). The conversion always begins with ADC  
Analog Input 0 and then progresses sequentially through the other selected ADC Analog  
Inputs.  
0000 = ADC Analog Input 0 updated.  
0001 = ADC Analog Inputs 0-1 updated.  
0010 = ADC Analog Inputs 0-2 updated.  
0011 = ADC Analog Inputs 0-3 updated.  
0100 = ADC Analog Inputs 0-4 updated.  
0101 = ADC Analog Inputs 0-5 updated.  
0110 = ADC Analog Inputs 0-6 updated.  
0111 = ADC Analog Inputs 0-7 updated.  
1000 = ADC Analog Inputs 0-8 updated.  
1001 = ADC Analog Inputs 0-9 updated.  
1010 = ADC Analog Inputs 0-10 updated.  
1011 = ADC Analog Inputs 0-11 updated.  
1100-1111 = Reserved.
