Note: VIL source < (GND - 0.3). Characterized but not tested. 5.5V < VIH source ≤ 5.8V. Characterized but not tested. If the sum of all injection currents are > \| ∑IICT \| it can affect the ADC results by approximately 4 to 6 counts (i.e., VIH Source > (VDDIO + 0.3) or VIL source < (GND - 0.3)). Any number and/or the combination of I/O pins not excluded under IICL or IICH conditions are permitted provided the “absolute instantaneous” sum of the input injection currents from all pins do not exceed the specified ∑IICT limit. To limit the injection current the user must insert a resistor in series RSERIES, (i.e. RS), between input source voltage and device pin. The resistor value is calculated according to: For negative Input voltages less than (GND-0.3): RS ≥ absolute value of \| ((VIL source - (GND - 0.3)) / IICL) \| For positive input voltages greater than (VDDIO + 0.3): RS ≥ absolute value of \| ((VIH source - (VDDIO + 0.3)) / IICH) \| For Vpin voltages >VDDIO +0.3 and <GND-0.3 then RS = the larger of the values calculated above. The following pins are High Sink pins and have different properties than standard pins: PA10, PA11, PB10, PB11. The following pins are TWIHS pins and have the same properties as standard pins when not used as SERCOM I²C pins: PA08, PA09, PA12, PA13, PA16, PA17, PA22, PA23. When used in SERCOM I²C mode, refer to I2CM_5/7 and I2CS_5/7 parameters.
