DRV8323R: DRV8323RH - PWM mode logic??
I open new thread, because the original thread is locked.
Could you check the logic using 1xPWM mode with DRV8323RH?
We are glad that we were able to resolve this issue, and will now proceed to close this thread.

In reply to Min-su Kim:
I showed the scope images in the previous thread.
GHx, GLx signal was cheked. But it was different from truth table with 1xPWM mode.
GHA is PWM, then GHB and GHC should be low.
But, GHC is high and GLC is low
you can see the scope iamges in the previous thread.
first scope image showed GHB and GLB when GHA was PWM.
GHB is low and GLB is high (<-- it means GHC and GLC should be low)
second scope image showed GHC and GLC when GHA was PWM.
GHC is high and GLC is low (<-- I think it is different from truth table.)
I use DRV8323RH(hardware-interface). I left the mode pins open.
I think motor wires and hall sensors are connected well. When I applied the power, motor rotates well.
But I wonder the gate signals.
Your hall inputs are probably not aligned with your motor inputs.
I'm sure that hall and motor input connection is correct.
You can see the movie clip using 1xPWM mode.
