2
Set up the ADC DMA control registers and buffer descriptors (UART channel D).
3
Reset the ADC module by writing a 0 then a 1 to bit 8 in the Module Reset
register at address A090 0180.
4
Flush the ADC DMA FIFO by writing a 1 then a 0 to bit 17 in UART Channel D
Wrapper Configuration register at address 9002 9000.
5
Enable the ADC DMA channel by writing a 1 then a 0 to bit 31 in the UART D DMA
RX Control register at address 9002 8004. 6. Start the ADC by writing a 1 to bit
31 in the ADC Configuration register at address 9003 9000.
