Dead-time Insertion
Figure 16-2. Timer/counter extensions and port override logic.
The dead-time insertion (DTI) unit generates OFF time where the non-inverted low side (LS) and
inverted high side (HS) of the WG output are both low. This OFF time is called dead time, and
dead-time insertion ensures that the LS and HS never switch simultaneously.
