Note 10:
After this period, the first clock pulse is generated.
Note 11:
The maximum t
HD:DAT
only has to be met if the device does not stretch the LOW period (t
LOW
) of the SCL signal.
Note 12:
A device must internally provide a hold time of at least 300ns for the SDA signal (see the V
IH MIN
of the SCL signal) to
bridge the undefined region of the falling edge of SCL.
Note 13:
C
B
—total capacitance of one bus line, timing referenced to 0.9 x V
CC
and 0.1 x V
CC
.
Note 14:
Guaranteed by design.
