(BD48, LD64)
In the following example, there is PWM duty change set to 50% of the period of output signal while inserting 2 pulses in each 8-cycle frame.

 MAIN.C

void main(void)
{
  PWM1_SetPWM(15);        /* change duty to 50% (16 / 32 counter ticks) */
  PWM1_SetBRM(2);         /* insert 2 pulses in the 8-cycle frame */
  
  for(;;){}
}

 MAIN.C

void main(void)
{
  PWM1_Disable();         /* disable device */
  PWM1_SetPhaseReg(64);   /* write delay value 64 */
  PWM1_EnablePhase();     /* enable automatic phase control */
  PWM1_Enable();          /* start pwm generation with phase difference */

  for(;;){}
}
