As a transmitter, the device must provide this internal minimum delay time to bridge the undefined region

receiving device.
Use Cb in pF for the calculations.
Not Tested
A Master Transmitter must provide a delay to ensure that difference between SDA and SCL fall times do
not unintentionally create a Start or Stop condition.
