4. VIL min and VIH max are reference values only and are not tested.
5. This parameter is characterized initially and after a design or process change that affects the parameter. Not 100% tested.
6. The total current sunk by all I/Os must be limited to 100 mA and each I/O limited to 25 mA maximum.
7. The total current sourced by all I/Os must be limited to 85 mA.
