1. All I/O pins are internally clamped to VSS through a ESD protection diode. There is no diode connection to VDD. If VIN

greater than VIO_MIN (= VSS-0.3 V) is observed, then there is no need to provide current limiting resistors at the pads. If this

limit cannot be observed then a current limiting resistor is required. The negative DC injection current limiting resistor is

calculated as R = (VIO_MIN - VIN)/|IICIO|.
