DMAA_ADDR—DMA_ADC Address
These bits specify the seven most-significant bits of the 12-bit Register File addresses
used for storing the ADC output data. The ADC Analog Input Number defines the five
least-significant bits of the Register File address. Full 12-bit address is
{DMAA_ADDR[7:1], 4-bit ADC Analog Input Number, 0}.
Reserved
This bit is reserved and must be 0.
DMA_ADC Control Register
The DMA_ADC Control register (Table 83) enables and sets options (DMA enable and
interrupt enable) for ADC operation.
