Note 11: A master device must provide a data hold time for SDA (referred to V
IL
of SCL) to bridge the undefined region of SCL’s
falling edge (see Figure 1).
Note 12: The minimum value is specified at T
A
= +25°C.
Note 13: C
B
= total capacitance of one bus line in pF.
Note 14: f
SCL
must meet the minimum clock low time plus the rise/fall times.
