FCap controls the size of the switched feedback capaci-
tor in the integrator.
ClockPhase controls the internal clock phasing relative
to the input clock phasing. ClockPhase affects the output
of the analog column bus which is controlled by the
AnalogBus bit in Control 2 Register (ASB11CR2,
ASB13CR2, ASB20CR2, ASB22CR2).

ASign controls the switch phasing of the switches on the
bottom plate of the A capacitor. The bottom plate sam-
ples the input or the reference.
The ACap bits set the value of the capacitor in the A
path.
