Due to limitations on the digital filter internal data path, there are some limitations on the combinations of the Sinc3 decimation factor (SF) and averaging factor (AF)
that can be used to generate a required ADC output rate. This restriction limits the minimum ADC update in normal power mode to 4 Hz or 1 Hz in lower power mode.
In low power mode and low power plus mode, the ADC is driven directly by the low power oscillator (131 kHz) and not 512 kHz. All f
by 4 (approx).
An additional time of approximately 60 μs per ADC is required before the first ADC is available.

Description
Sinc3 Modify. Set by the user to modify the standard Sinc3 frequency response to increase the filter stop band
rejection by approximately 5 dB. This is achieved by inserting a second notch (NOTCH2) at

Sinc3 filter. The output rate from the Sinc3 filter is given by
when the chop bit (Bit 15, chop enable) = 0 and the averaging factor (AF) = 0. This is valid for all SF values ≤ 125.
