A device must internally provide a hold time of at least 300 ns for I2DAT signal in order to bridge the undefined region of the
falling edge of I2CLK.
The maximum hold time has to be met only if the device does not stretch the LOW period (ID IC6) of the I2CLK signal.
A Fast-mode I2C-bus device can be used in a standard-mode I2C-bus system, but the requirement of set-up time (ID IC7) of
250 ns must then be met. This will automatically be the case if the device does not stretch the LOW period of the I2CLK signal.
If such a device does stretch the LOW period of the I2CLK signal, it must output the next data bit to the I2DAT line max_rise_time
(ID No IC10) + data_setup_time (ID No IC8) = 1000 + 250 = 1250 ns (according to the Standard-mode I2C-bus specification)
before the I2CLK line is released.
