1 The master mode I2C deasserts ACK of an address byte simultaneously with the falling edge of SCL. If no slaves
acknowledge this address byte, a negative hold time can result, depending on the edge rates of the SDA and SCL lines.

3 A Fast mode I2C bus device can be used in a Standard mode I2C bus system, but the requirement t
SU; DAT > = 250 ns must
then be met. This is automatically 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 = 1250 ns (according to the Standard mode I
2C bus specification) before the SCL line is released.
