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

SDON: S/D Module Enable bit
1 = Module is enabled
0 = Module is disabled
Unimplemented: Read as ‘0’
SDSIDL: S/D Stop in Idle Mode bit
1 = Discontinues module operation when device enters Idle mode
0 = Continues module operation in Idle mode
SDRST: S/D Reset bit
1 = Resets all S/D module circuitry (analog section remains in Reset as long as bit is set)
0 = Releases from Reset (Run mode)
Reserved: Maintain as ‘0’ for proper operation
SDGAIN<2:0>: S/D Gain Control bits
11x = Reserved
101 = 32
100 = 16
011 = 8
010 = 4
001 = 2
000 = 1
DITHER<1:0>: Dither Mode Select bits
11 = High dither (preferred with higher Oversampling Ratio (OSR) and positive reference well below SVDD)
10 = Medium dither (preferred for low to medium OSR and positive reference well below SVDD)
01 = Low dither (preferred when the positive reference is at or near SVDD)
00 = No dither
Unimplemented: Read as ‘0’
VOSCAL: Internal Offset Measurement Enable bit
1 = Converter is configured to sample its own internal offset error
0 = Converter is configured for normal operation
Unimplemented: Read as ‘0’
SDREFN: S/D Negative Reference Source Select bit
1 = SVREF- pin
0 = SVSS pin
SDREFP: S/D Positive Reference Source Select bit
1 = SVREF+ pin
0 = SVDD pin
PWRLVL: Analog Amplifier Bandwidth Select bit
1 = 2x bandwidth (higher power consumption compared to normal bandwidth)
0 = Normal bandwidth
