15.2.4 Runt Pulse Indication

A runt pulse PWM event can be configured similarly to 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 the 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 complementary output to compensate for the pulse stretching and to protect the application circuits.
