Parameters
This parameter is ensured by characterization and not 100% tested.
This specification is not a part of the I2C specification. This specification is equivalent to the Data Hold Time (
plus SDA Fall (or rise) time:
If this parameter is too short, it can create an unintended Start or Stop condition to other devices on the bus line. If this
parameter is too long, Clock Low time (T
For Data Input: This parameter must be longer than t
Clock Low time (T
For Data Output: This parameter is characterized, and tested indirectly by testing T
All timing parameters in high-speed modes are tested at V
