Note:

VIL source < (GND - 0.6). Characterized but not tested.
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, PC16, PC17, PA22, PA23. When used in SERCOM I²C mode, refer to I2CM_5/I2CM_7 and I2CS_5/I2CS_7 parameters.
Rising and falling measurements given between 10% and 90%.
