9.1
Reset
A 1-bit value to initialize the L3-bus and I
2
C-bus registers
except the system register (00H) with default settings by
setting bit RST = 1.
Table 20
Reset bit
9.2
Quick mode switch
A 1-bit value to enable the quick mode change of the ADC.
The soft mode change works only between modes if
bit AM2 = 1.
Table 21
Quick mode switch
9.3
Bypass mixer DC filter
A 1-bit value to disable the DC filter of the ADC mixer. This
DC filter is in front of the mixer to prevent clipping inside
the mixer due to DC signals.

Mixer DC filtering
9.4
DC filter
A1-bitvaluetoenabletheDC filteroftheADCoutput.This
DC filter is inside the decimation filter.

9.5
ADC mode
A 3-bit value to select the mode of the ADC.

ADC mode
9.6
ADC polarity
A 1-bit value to control the ADC polarity.
