bit 7
bit 0
Legend:
R = Readable bit
R = Readable bit
W = Writable bit
U = Unimplemented bit, read as ‘0’
-n = Value at POR
‘1’ = Bit is set
‘0’ = Bit is cleared
x = Bit is unknown
bit 15-7
Unimplemented: Read as ‘0’
bit 8
ADDMAEN: ADC DMA Enable bit
1 = Conversion results stored in ADCxBUF0 register, for transfer to RAM using DMA
0 = Conversion results stored in ADCxBUF0 through ADCxBUFF registers; DMA will not be used
1 = Conversion results stored in ADCxBUF0 register, for transfer to RAM using DMA
0 = Conversion results stored in ADCxBUF0 through ADCxBUFF registers; DMA will not be used
