Legend:
R = Readable bit
-n = Value at POR
C = Clearable bit
W = Writable bit
‘1’ = Bit is set
U = Unimplemented bit, read as ‘0’
HSC = Hardware Settable/Clearable bit
‘0’ = Bit is cleared
x = Bit is unknown

ADON: A/D Operating Mode bit
1 = A/D Converter is operating
0 = A/D Converter is off
Unimplemented: Read as ‘0’
ADSIDL: A/D Stop in Idle Mode bit
1 = Discontinues module operation when device enters Idle mode
0 = Continues module operation in Idle mode
DMABM: Extended DMA Buffer Mode Select bit⁽¹⁾
1 = Extended Buffer mode: Buffer address is defined by the DMADSTn register
0 = PIA mode: Buffer addresses are defined by the DMA Controller and AD1CON4<2:0>
DMAEN: Extended DMA/Buffer Enable bit
1 = Extended DMA and buffer features are enabled
0 = Extended features are disabled
MODE12: A/D 12-Bit Operation Mode bit
1 = 12-bit A/D operation
0 = 10-bit A/D operation
FORM<1:0>: Data Output Format bits (see formats following)
11 = Fractional result, signed, left justified
10 = Absolute fractional result, unsigned, left justified
01 = Decimal result, signed, right justified
00 = Absolute decimal result, unsigned, right justified
SSRC<3:0>: Sample Clock Source Select bits
0000 = SAMP is cleared by software
0001 = INT0
0010 = Timer3
0100 = CTMU trigger
0101 = Timer1 (will not trigger during Sleep mode)
0110 = Timer1 (may trigger during Sleep mode)
0111 = Auto-Convert mode
Unimplemented: Read as ‘0’
ASAM: A/D Sample Auto-Start bit
1 = Sampling begins immediately after last conversion; SAMP bit is auto-set
0 = Sampling begins when SAMP bit is manually set
Note 1: This bit is only available when Extended DMA and buffer features are available (DMAEN = 1).
