Inputs and outputs are protected against electrostatic discharge in normal handling. However, it is good practice to take
normal precautions appropriate to handling MOS devices (see “Handbook IC03, Section: General, Handling MOS
devices” ).

PARAMETER
The time that the bus is free (SDA is
HIGH) before a new transmission is
initiated by SDA going LOW.
Only valid for repeated start code.
The time between SDA going LOW and
the first valid negative-going transition of
SCL.
The LOW period of the SCL clock.
The HIGH period of the SCL clock.
