Please help me to understand the below back emf and hall waveforms and how to drive motor.Motor data sheet

For the 1st 60 degrees

C+, A- Here the voltage is in the positive direction and C phase shall be High compared to A phase and hence 100% duty to A phase and 0% duty to C phase.

A+, B- here the voltage is in the negative direction and hence A phase voltage shall be less than B phase, hence A shall be Ground compared to B and B can be 100% duty.

B+, C- here the voltage is positive and hence B+ shall be 100% duty compared to C and C to be ground.

Please help me to clear this and drive the motor.
