(1) All timing is with 6-mA drive and 20-pF load.
(2) This value depends on the value programmed in the clock period register of I²C. Maximum output frequency is the result of the minimal
value programmed in this register.
(3) Because I²C is an open-drain interface, the controller can drive logic 0 only. Logic is the result of external pullup. Rise time depends on
the value of the external signal capacitance and external pullup register.
