Booster output pin. This circuit generates a voltage about 1.5 V above that of the
VSPN pin.
Booster pumping capacitor connection
Spindle driver current detection

Spindle and booster power supply
W phase low pass filter. Connect a filter C to this pin during GND.
V phase low pass filter. Connect a filter C to this pin during GND.
U phase low pass filter. Connect a filter C to this pin during GND.
Reference voltage of spindle and slide
Spindle control input. Generates forward torque when a DC voltage higher than
REFIN is applied, and brake when a DC voltage lower than REF is applied.
For AGC. Holds the level used for IC internal processing fixed even if the B-EMF
level fluctuates due to the rotation speed.
