Running mode:
In running mode the output is triggered by the comparator. An offset cancellation
feedback loop is formed by the A/D converter, dsp and offset cancellation D/A
converter. In running mode switching always occurs at zero-crossing. It is only
affected by the (small) remaining offset of the comparator and by the remaining
propagation delay time of the signal path, mainly determined by the noise-
shaping filter. Nevertheless signals below a defined threshold are not detected to
avoid unwanted parasitic switching.

Figure 3: Startup of the device
At transition from startup-mode to running mode switching timing is moving
from low-accuracy to high accuracy zero-crossing.
