DRV8320: How to control motor BLDC follow "sensored trapezoidal motor control" use DRV8320S

Part Number: DRV8320

Tool/software:

I want to control a BLDC motor using "sensored trapezoidal motor control" method. According to the motor commutation diagram, at any given time, two phases are energized while one phase is "disabled."

However, when using the DRV8320SRTVR, disabling one phase is not possible as expected. I have tried the method such as setting "INHx = GND and INLx = 3.3V", but this only results in only three valid commutation states remain.

How can I properly implement "sensored trapezoidal motor control" for a BLDC motor using the DRV8320?

Regards,
