DRV8323: 1-PWM mode is not working

Part Number:DRV8323

Hi,

I am having a difficulty to run BLDC motor using 1-PWM mode (using MCU signals).

6-PWM mode is working correctly, so I am probably missing some "initialization algorythm" or something.

I set 20kHz PWM signal on INHA, High state on INLC, Low state on INHC and then I am shiffting between 6 commutation states, but OUTPUT is set low, no metter which state it is.

Could you tell me if there are any conditions that I didn't satisfy or present mi some sample code of using 1-PWM mode.

Thanks in advance,

Igor
