Note: VIL source < (VSS - 0.3). Characterized but not tested. VIH source > (VDD + 0.3). 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 > (VDD + 0.3) or VIL source < (VSS - 0.3)). Any number and/or 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 (VSS - 0.3): RS ≥ absolute value of \| ((VIL source - (VSS - 0.3)) / IICL) \| For positive input voltages greater than (VDD + 0.3): RS ≥ ((VIH source - (VDD + 0.3))/ IICH) For Vpin voltages >VDD + 0.3 and <VSS - 0.3 then RS = the larger of the values calculated above High Sink I/O pins are: PA08, PA09, PA12, PA13, PA16, PA17, PA22, PA23, PA31, PB12, PB13, PB16, PB17, PB30, PB31.
