Note 7:
After this period, the first clock pulse is generated.
Note 8:
The maximum t
has only to be met if the device does not stretch the LOW period (t
) of the SCL signal.
Note 9:
A fast-mode device can be used in a standard mode system, but the requirement t
SU:DAT
>250ns 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 t
RMAX
+ t
SU:DAT
(1000 + 250 = 1250ns) before the SCL line is released.
