1. The I2C characteristics are the requirements from I2C bus specification rev03. They are guaranteed by design when
2. The maximum Data hold time has only to be met if the interface does not stretch the low period of SCL signal.
3. The device must internally provide a hold time of at least 300ns for the SDA signal in order to bridge the undefined region of
