Applying a voltage to NC pins does not cause any problem since they are not connected inside the IC.
All control input pins have an internal pull-down resistor of 100 kΩ (typ.)

Except the above pins, all pins are NC. The pin numbers of NC pins are: 1, 12, 13, 14, 16, 18, 20, 21, 23, 24, 25,
TB6560AFTG as possible.
The electrical characteristics provided in this document are measured when those pins are handled in this
manner.)
