The serial port is required the 11 bit data (D0 to D9 and A0). Address bit A0 is used to select the register
as follows. When the data length is less than 11 bits, the internal register will not be up dated. And when
the data length is more than 11 bits, this register will take late 10 bits and ignore the faster bit.

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.
