DS90UB948-Q1: Rise / fall time difinition for SDA/SCL

Part Number: DS90UB948-Q1

Hi team,

Could you tell me the definition of tf and tr for SDA and SCL?

Does tf and tr means the transition time between VIH(min) and VIL(max)?

(ex) VIH(max)=2V, VIL(max)=0.9V when VDDIO = 3.0V to 3.6V.

It looks the I2C specification(UM10204) specifies tr and tf as the transition time between 0.3VDD and 0.7VDD.

So, I want to make sure which definition is true for this device.

Regards,

Saito
