As a transmitter, the device must provide this internal minimum delay time to bridge the undefined region (min. 300 ns)
of the falling edge of SCLx to avoid unintended generation of Start or Stop conditions.
A Fast mode I
must then be met. This will automatically be the case if the device does not stretch the LOW period of the SCLx signal.
If such a device does stretch the LOW period of the SCLx signal, it must output the next data bit to the SDAx line,
T
line is released.
