1. All 5 V tolerant digital I/O pins are internally clamped to VSS through an ESD protection diode. There is no diode
connection to VDD. If VIN is less than VDIO_MIN, a current limiting resistor is required. The negative DC injection current
limiting resistor is calculated as R=(VDIO_MIN-VIN)/|IICDIO|.
2. Analog pins are defined as pins that do not have an associated general purpose I/O port function. Additionally, EXTAL and
XTAL are analog pins.
3. All analog pins are internally clamped to VSS and VDD through ESD protection diodes. If VIN is less than VAIO_MIN or greater
than VAIO_MAX, a current limiting resistor is required. The negative DC injection current limiting resistor is calculated as
R=(VAIO_MIN-VIN)/|IICAIO|. The positive injection current limiting resistor is calculated as R=(VIN-VAIO_MAX)/|IICAIO|. Select the
larger of these two calculated resistances if the pin is exposed to positive and negative injection currents.
4. Open drain outputs must be pulled to VDD.
