Example:

    /* Get pattern error flag */
    (void) RM_MOTOR_120_CONTROL_SENSORLESS_PatternErrorFlagGet(g_motor_120_control_sensorless0.p_ctrl,
                                                               &smpl_pattern_error_flag);

Return values

FSP_SUCCESS	Successfully resetted.
FSP_ERR_ASSERTION	Null pointer.
FSP_ERR_NOT_OPEN	Module is not open.
FSP_ERR_INVALID_ARGUMENT	Input parameter error.
