* These parameters are characterized but not tested.
Note 1:
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.
2:
A Fast mode (400 kHz) I2C bus device can be used in a Standard mode (100 kHz) I2C bus system, but
the requirement TSU:DAT
250 ns 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 sig-
nal, it must output the next data bit to the SDAx line TR max. + TSU:DAT = 1000 + 250 = 1250 ns (according
to the Standard mode I2C bus specification), before the SCLx line is released.
