1 Guaranteed by initial characterization. All values measured with input filtering enabled. CB refers to capacitive load on the bus line; tR and tF are measured between
0.3 VDD and 0.7 VDD.
2 High speed I2C is available only in -HS models
3 A device must provide a data hold time for SDA to bridge the undefined region of the SCL falling edge.
