I have created a project and have the output working to a point using the help file with the POSHL001 APP. right now I have the hall pattern and motor pattern functioning correctly as I rotate the motor and hall pattern is updated, but the output that will go to the driver has modulation working on all 6 lines. I am trying for high side PWM I have modulation going the the 3 high side fets but the low siide that should not have modulation are also being modulated. What signal or other mapping is needed? Using the 8 bit you would create a modulation pattern and output pattern but not sure how that is accomplished in the APP.
