When an output changes from driving high to driving low, or driving low to driving high, dead time is automatically inserted to prevent shoot-through. tDEAD is the time in the middle when the output is High-Z. If the output pin is measured during tDEAD, the voltage will depend on the direction of current. If current is leaving the pin, the voltage will be a diode drop below ground. If current is entering the pin, the voltage will be a diode drop above VM. This diode is the body diode of the high-side or low-side FET.
