17.4.2.4.3 Burst Mode
In some applications, it is desirable to have the PWM cycle repeat a certain number of times after the PWM Generator is triggered. The TRGCNT[2:0] control bits (PGxCON[10:8]) select the number of times the PWM cycle will be repeated after a trigger event. Any incoming triggers will be ignored until all PWM cycles are completed. Use of Retriggerable mode in conjunction with Burst mode is not recommended.
