DRV8935PEVM: DRV8935PEVM PWM and STEP Mode Behavior with Unipolar and Bipolar Motors

Tool/software:

Hi TI support Team,

I’m testing the DRV8935PEVM and using a Unipolar motor as the load.
In PWM mode, how should IN1 ~ IN4 be configured? What is the meaning of the 0%–100% range?

Also, when testing with a Bipolar motor as the load and setting the DRV8935 to STEP mode,
why is the motor able to work?

Thanks!
