14.2 I2C-bus timing characteristics
Table 54. I2C-bus timing characteristic
VDD1, VDD2, VDD3 = 2.5 V to 5.5 V; VSS1 = 0 V; VLCD = 4.0 V to 12.0 V; Tamb = 40 C to +105 C; unless otherwise specified.
All timing values are valid within the operating supply voltage and ambient temperature range and are referenced to VIL and
VIH with an input voltage swing of VSS1 to VDD1.
