Note 1.

This is approximately equal to tLOWmin + tDS_ODmin + trDA_ODtyp + tSU_ODmin.

Note 2.

The Master may use a shorter Low period if it knows that this is safe, i.e., that SDA is already above VIH.

Note 3.

This is based on tSPIKE, rise and fall times, and interconnect.

Note 4.

This maximum High period may be exceeded when the signals can be safely seen by Legacy I2C Devices, and/or in

consideration of the interconnect (e.g., a short bus).

Note 5.

On a Legacy Bus where I2C Devices need to see Start.

Note 6.

Slaves that do not support the optional ENTASx CCCs shall use the tCAS Max value shown for ENTAS3

Note 7.

On a Mixed Bus with Fm Legacy I2C Devices, tAVAL is 300 ns shorter than the Fm Bus Free Condition time (tBUF)
