(1) fMASTER, must be at least 8 MHz to achieve max fast I2C speed (400kHz)

(2) Data based on standard I2C protocol requirement, not tested in production

(3) The maximum hold time of the start condition has only to be met if the interface does not stretch the

low time

(4) The 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 falling edge of SCL
