Notes

1. 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
calculated as R=(VIN-VAIO_MAX)/|IIC|. Select the larger of these two calculated resistances.
