PARAMETER
All voltages are referenced to ground.
Limits at -40°C are guaranteed by design and are not production tested.
I
After this period, the first clock pulse is generated.
A device must internally provide a hold time of at least 300ns for the SDA signal (referred to the V
signal) to bridge the undefined region of the falling edge of SCL.
