SCL clock frequency.
Hold time ( repeated ) Start condition.
After this period, the first clock pulse is generated.
Low period of the SCL clock.
High period of the SCL clock.
Set-up time for a repeated START condition.
Data hold time. For I2C-bus device.
Data set-up time.
Rise time of both SDA and SCL signals.

t_r
Fall time of both SDA and SCL signals.
Set-up time for STOP condition.
Bus free time between a STOP and START.
Capacitive load for each bus line.
Noise margin at LOW level for each connected device.
( Including hysteresis )
Noise margin at HIGH level for each connected device.
( including hysteresis )
Note : It depends on the “high” period time of SCL.
