(1) _{fMASTER, must be at least 8 MHz to achieve max fast I}2_{C speed (400kHz).}
(2) _{Data based on standard I}2_{C 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.
