Notes:

7. In “Normal spinning, the FG changes its state at each edge of O1.

8. When the motor locks with South pole at the Hall element, O2 is kept on “L” and O1 is a clock with Ton/Toff ratio. When motor locks with North pole

at the Hall element, O1 is kept on “L”, O2 is a clock with Ton/Toff ratio.

9. When “Re-start spinning” occurs, the motor speed ramps up to the “Normal Spinning” speed from zero. Speed ramp-up profile depends on motor

characteristics.

10. X: H or L depends on magnetic pole north or South
