Note:
(1) Value guaranteed by design.
(2) The ST9 device must internally provide a hold time of at least 300 ns for the SDA signal in order to bridge the undefined region of the fall-
(3) The maximum hold time of the START condition has only to be met if the interface does not stretch the low period of SCL signal
Legend:
Tck = INTCLK period = Crystal Oscillator Clock period when CLOCK1 is not divided by 2;
Cb = total capacitance of one bus line in pF
FREQ[2:0] = Frequency bits value of I
