Legend:
R = Readable bit
-n = Value at POR
W = Writable bit
â1â = Bit is set
U = Unimplemented bit, read as â0â
â0â = Bit is cleared
x = Bit is unknown

bit 2-0
Unimplemented: Read as â0â
DMABL<2:0>: DMA Buffer Size Select bits(1)
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
Note 1: The DMABL<2:0> bits are only used when AD1CON1<11> = 1 and AD1CON1<12> = 0; otherwise, their
value is ignored.
