in connection with the frequency of PWM signal. Be especially careful when the IC is used for high-speed
motors.
phase is turned on by the timing of the next PWM signal.
Since positional detection is performed in synchronization with PWM signal, positional variation occurs
Variation is calculated through detection at two consecutive rising edges of the PWM signal.
