TMS320F28374D: Floating Pin

Giacomo,

There is no special logic to indicate that the pin is floating. The indication is Binary, and does not indicate if the voltage is between VIL and VIH.

Stated another way: The input pins will indicate a logic 0 if the voltage crossed below VIL and a 1 if the the voltage crossed above VIH. If the voltage on the pin is somewhere between VIL and VIH it will continue to indicate the last state.

For example: If the voltage stars off at 0V then slowly drifts above VIL it will still indicate a 0. If the voltage later drifts or is pulled above VIH then a logic 1 will be indicated.
