DRV10866 State turn in Open loop

Hi,

I have a question about DRV10866 State turn in Open loop
In datasheet, There is the following words.
“At start-up with motor at standstill, commutation logic starts to drive the motor in open-loop with U-phase high, Vphase low, and the W-phase shut off. During open-loop start-up phase, commutation logic advance to next state automatically as per Table 1 with duty cycle of 100% regardless of PWM input. ”

I think first state is State1.
Is next state of state1 “State6”? I though from the following picture.
This picture is start up waveform.


Best regards,
Shimizu
