All 5 V tolerant digital I/O pins are internally clamped to VSS through a ESD protection diode. There is no diode connection to VDD. If VIN greater than VDIO_MIN (=VSS-0.3V) 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=(VDIO_MIN-VIN)/|IIC|. 2. Analog pins are defined as pins that do not have an associated general purpose I/O port function. 3. All analog pins are internally clamped to VSS and VDD through ESD protection diodes. If VIN is greater than VAIO_MIN (=VSS-0.3V) and VIN is less than VAIO_MAX(=VDD+0.3V) is observed, then there is no need to provide current limiting resistors at the pads. If these limits cannot be observed then a current limiting resistor is required. The negative DC injection current limiting resistor is calculated as R=(VAIO_MIN-VIN)/|IIC|. The positive injection current limiting resistor is calcualted as R=(VIN-VAIO_MAX)/|IIC|. Select the larger of these two calculated resistances. General K10 Sub-Family Data Sheet, Rev. 2, 4/2012.
