In Fast-mode Plus, fall time is specified the same for both output stage and bus timing. If series resistors
are used, designers should allow for this when considering bus timing.

data must be valid by the set-up time before it releases the clock.
tSU;DAT is the data set-up time that is measured with respect to the rising edge of SCL; applies to data in
transmission and the acknowledge.
250 ns must then be met. This will automatically be the case if the device does not stretch the LOW period
of the SCL signal. If such a device does stretch the LOW period of the SCL signal, it must output the next
data bit to the SDA line t
