15.4.1.4 Runt Pulse Indication

A runt pulse PWM event can be configured similarly as other PWM events discussed in PWM Event Outputs. To configure the runt pulse event, set PWMEVTy.EVTySEL[4:0] = 11010. When a runt pulse is detected on any of the input channels, the runt pulse event signal is asserted high for one cycle to inform the application of the condition if the event is configured.

When runt pulse indication is asserted, the output also indicates pulse stretching to prevent the runt pulse from reaching the application. If dead time is also configured, it is automatically preserved. The additional dead time is added to the complimentary output to compensate for the pulse stretching to protect the application circuits.
