Notes: 1. The spindle motor is independently winding to the value of the MD2, during the MD1 is true.
2. The bit MD4 select a commutation mode at driving by B-EMF sensing. (See Commutation
timing)
3. In order to prevent the misdetection of back-EMF amplifier, the bit MD8 should be chosen as
shown above table.
4. The bit MD9 determine the operating frequency of Booster Circuit. According to the frequency of
Input CLK at pin 10, the value of MD9 should be chosen as shown below.
