1. A device must internally provide a hold time of at least 300ns for the SDA signal (referred to the VIH min of the SCL signal) to
bridge the undefined region of the falling edge of SCL.

2. The maximum tHD; DAT has only to be met if the device does not stretch the LOW period (tLOW) of the SCL signal.

3. A Fast mode I2C bus device can be used in a Standard mode I2C bus system, but the requirement tSU; DAT > = 250ns 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
trmax + tSU; DAT = 1000 + 250 = 1250ns (according to the Standard mode I
2C bus specification) before the SCL line is released.
