DMA Status Register  
The DMA Status register indicates the DMA channel that generated the interrupt and the  
ADC Analog Input that is currently undergoing conversion. Reads from this register reset  
the Interrupt Request Indicator bits (IRQA, IRQ1, and IRQ0) to 0. Therefore, software  
interrupt service routines that read this register must process all three interrupt sources  
from the DMA.

CADC[3:0]—Current ADC Analog Input  
This field identifies the Analog Input that the ADC is currently converting.  
Reserved  
This bit is reserved and must be 0.  
IRQA—DMA_ADC Interrupt Request Indicator  
This bit is automatically reset to 0 each time a read from this register occurs.  
0 = DMA_ADC is not the source of the interrupt from the DMA Controller.  
1 = DMA_ADC completed transfer of data from the last ADC Analog Input and generated  
an interrupt.  
IRQ1—DMA1 Interrupt Request Indicator  
This bit is automatically reset to 0 each time a read from this register occurs.  
0 = DMA1 is not the source of the interrupt from the DMA Controller.  
1 = DMA1 completed transfer of data to/from the End Address and generated an interrupt.  
IRQ0—DMA0 Interrupt Request Indicator  
This bit is automatically reset to 0 each time a read from this register occurs.  
0 = DMA0 is not the source of the interrupt from the DMA Controller.  
1 = DMA0 completed transfer of data to/from the End Address and generated an interrupt.
