DMABL<2:0>
bit 0
Legend:
R = Readable bit
-n = Value at POR
W = Writable bit
‘1’ = Bit is set
U = Unimplemented bit, read as ‘0’
‘0’ = Bit is cleared
x = Bit is unknown
bit 15-9
bit 8
bit 7-3
bit 2-0
Unimplemented: Read as ‘0’
ADDMAEN: ADC DMA Enable bit
1 = Conversion results are stored in ADCxBUF0 register for transferring to RAM using DMA
0 = Conversion results are stored in ADCxBUF0 through ADCxBUFF registers; DMA will not be used
Unimplemented: Read as ‘0’
DMABL<2:0>: Selects Number of DMA Buffer Locations per Analog Input bits
111 = Allocates 128 words of buffer to each analog input
110 = Allocates 64 words of buffer to each analog input
101 = Allocates 32 words of buffer to each analog input
100 = Allocates 16 words of buffer to each analog input
011 = Allocates 8 words of buffer to each analog input
010 = Allocates 4 words of buffer to each analog input
001 = Allocates 2 words of buffer to each analog input
000 = Allocates 1 word of buffer to each analog input
