6.4.1.2 Active-Turns Mode

In this mode, the AMR sensor outputs are active and the turns counter is enabled. In this mode, the TURNS pin acts as a I/O and provides the counter information using the PWM output. In this mode, the Hall sensors are enabled and the outputs are monitored to update the turns counter. To enter this mode, the TURNS pin is pulled low for t > ttc_start. Figure 6-15 shows the sequence to enter active-turns mode. After the TURNS pin is released, the falling edge of the first PWM pulse occurs after ttc_start. To exit this mode, the TURNS pin is pulled low for t > ttc_reset as defined in the Specifications section. After the turns counter is reset, the part goes back into active mode.
