This function sets the triangular wave cycle (carrier cycle) necessary for generating the PWM signal.
(The triangular wave is used for forcibly turning on the lower transistor when the motor is driven by
This function detects the motor rotation direction every electrical angle of 360°. This function judges
*: CW or CCW of the motor is determined by the direction of the Hall signal, which is specified in the timing
*: When the REV pin is set to LOW, and the Hall signal is higher than 5 Hz, sine-wave drive mode is turned

When the DC-link-current exceeds the internal reference voltage, gate block protection is performed.
Reference voltage = 0.5 V (typ.)
Output is turned off when the positional signal is HHH or LLL; otherwise, it is restarted.
