Timing Characteristics
Between each magnetic transition and the rising edge of the corresponding output pulse, the output current
is low for t_pre-low in order to allow reliable internal conveyance. After pre low time the output current level is set
to high.
After power on the speed pulse is being issued. As soon as the sensor has enough information to recognize the
direction of the target wheel, the output pulse will include the direction information.
