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

ADON: A/D Operating Mode bit
1 = A/D Converter module is operating
0 = A/D Converter is off
Unimplemented: Read as ‘0’
ADSIDL: Stop in Idle Mode bit
1 = Discontinue module operation when device enters Idle mode
0 = Continue module operation in Idle mode
DMABM: Extended DMA Buffer Mode Select bit⁽¹⁾
1 = Extended Buffer mode: Buffer address is defined by the DMAnDST 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: 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
1xxx = Unimplemented, do not use
0111 = Internal counter ends sampling and starts conversion (auto-convert). Do not use in
Auto-Scan mode
0110 = Unimplemented
0101 = TMR1
0100 = CTMU
0011 = TMR5
0010 = TMR3
0001 = INT0
0000 = The SAMP bit must be cleared by software to start conversion
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/Buffer features are available (DMAEN = 1).
