4Description:
5		This attribute is used to set the gain of the biasing current
6		circuit of the Delta-Sigma modulator. The different BOOST
7		settings are applied to the entire modulator circuit, including
8		the voltage reference buffers.

20Description:
21		This attribute is used to enable the analog input multiplexer
22		auto-zeroing algorithm (the input multiplexer and the ADC
23		include an offset cancellation algorithm that cancels the offset
24		contribution of the ADC). When the offset cancellation algorithm
25		is enabled, ADC takes two conversions, one with the differential
26		input as VIN+/VIN-, one with VIN+/VIN- inverted. In this case the
27		conversion time is multiplied by two compared to the default
28		case where the algorithm is disabled. This technique allows the
29		cancellation of the ADC offset error and the achievement of
30		ultra-low offset without any digital calibration. The resulting
31		offset is the residue of the difference between the two
32		conversions, which is on the order of magnitude of the noise
33		floor. This offset is effectively canceled at every conversion,
34		so the residual offset error temperature drift is extremely low.
35		Write '1' to enable it, write '0' to disable it.

40Description:
41		This attribute is used to enable the chopping algorithm for the
42		internal voltage reference buffer. This setting has no effect
43		when external voltage reference is selected.
44		Internal voltage reference buffer injects a certain quantity of
45		1/f noise into the system that can be modulated with the
46		incoming input signals and can limit the SNR performance at
47		higher Oversampling Ratio values (over 256). To overcome this
48		limitation, the buffer includes an auto-zeroing algorithm that
49		greatly reduces (cancels out) the 1/f noise and cancels the
50		offset value of the reference buffer. As a result, the SNR of
51		the system is not affected by this 1/f noise component of the
52		reference buffer, even at maximum oversampling ratio values.
53		Write '1' to enable it, write '0' to disable it.
