MCF8316A: Motor is not rotating with lesser PWM command

Dear Team,

We made a motor driver board after evaluating the motor in MCF8316A EVM board.

e2e.ti.com/.../Reg_5F00_sep22.txt

Register files are attached for your reference. The motor is not running with lesser duty cycle but rotates with 80% duty cycle.

at 80% input.

 at 30% input.

Any idea why the motor is stuck at ISD state?

Thanks and Regards,

Sujeesh V
