PWM oscillator frequency setting.
Connect a capacitor between this pin and ground.
VCO PLL filter connection
Sets the value of the charge current from the VCO circuit C
pin.
Insert a resistor between this pin and ground.
Torque command input
Normally, this pin is connected to the INT.OUT pin. The
PWM duty is increased when the TOC pin voltage falls.
Do not apply a voltage that exceeds V
(An input from a normal operational amplifier is desirable.)
