C2000WARE: how can I set the motor PWM sequence if I got the hall sensor sequence?

Part Number: C2000WARE

I have a BLDC motor, it has 3 hall sensors in 120 degree position. i tested hall sensor sequence is: 110,010,011,001, 101,100, and in reverse direction, the hall sensor sequence is 001,011, 010,110,100, 101. pls help check if these sequence are correct or not?

if the hall sensor sequence is correct, what PWM sequence I need to give to the motor in both direction?

thanks

if I use the wrong PWM sequence, what will happen? will I burn or damage my motor?

That depends on the wires connection of both the motor and hall sensors, unfortunately, we are difficult to tell you the answer if you are not using the TI EVM kit and bundled motor. You may try to find the control logic yourself, the motor can't run smoothly, even stall and over current if the logic is not correct.
