Figure 7.
The 4-bit A/D has an internal hysteresis so that "Analog high thresholds" are the A/D
thresholds applying a rising edge on TO pin, the "Analog low thresholds" are the A/D
thresholds applying a falling edge on TO pin.
The applied phase shift "moves" the voltage profile with respect to the Hall effect sensor in
the direction indicated by the arrows in the picture.
