DESCRIPTION
This bit sets the minimum length of time devoted for detecting a zero crossing
(advanced use only).

1: 200 µs
2: 300 µs
3: 390 µs
This bit sets the length of the auto calibration time. The AUTO_CAL_TIME[1:0]
bit should be enough time for the motor acceleration to settle when driven at the
RATED_VOLTAGE[7:0] value.

1: 250 ms (minimum), 450 ms (maximum)
2: 500 ms (minimum), 700 ms (maximum)
